2017; Vicente, Jakobsson, et al. A central premise of precision medicine is that ancestral variation plays a key role in disease processes. 2020; Schlebusch et al. 2013; Chimusa et al. 2018). 2018). Interestingly, there is less differentiation between the African ancestries found in admixed genomes in the Americas (as quantified by FST statistics) compared with what is seen between each of the contributing ancestries in Africa (Gouveia et al. 2012). Once These studies have shown that a patient's demographic medical and genetic information can be used for clinical decision-making or genetic counseling (Batai et al. 2017; Swart et al. Attempts to illuminate the deep population structure in Africa have been further aided by the emergence of ancient DNA from unadmixed huntergatherer individuals (e.g., Skoglund et al. 2012; Arauna et al. Genetic counselors are certified professionals who help patients understand the results of genetic testing. Genetic differentiation in East African ethnicities and its - PLOS 2..The secret lies in certain parts of their DNA. 4A; Prendergast et al. 2017). 2015). 5. Note that subsequent gene flow can confound these estimates. For example, population-specific recombination maps have the potential to advance the detection of genotypephenotype correlations in admixed populations and further the field of precision medicine relevant to all populations (Choudhury et al. This understanding together with knowledge of its interactions with sociocultural factors that influence disease risk or treatment response can improve clinical care by improving the accuracy of genetic testing and/or assessment of therapeutic response (Hindorff et al. The amount of gene flow from wBSPs into individual RHG groups varied. Christian Kwon - Head of Sales Development - Seqera Labs The genetic relationship between these different huntergatherer groups can largely be modeled by an isolation-by-distance model (Skoglund et al. This work was supported by an NIGMS MIRA grant to J.L. Many huntergatherer groups experienced declines in Ne during the Holocene and have small census population sizes today (Patin et al. 2017). 2014; Macholdt et al. Genetic studies of uniparental and autosomal markers initially suggested that BSPs are largely genetically homogenous groups of people (i.e., FST 0.02) (Coelho et al. 2009; Schlebusch et al. East African genetics at work. - Bodybuilding.com Forums Discover east african genetics bodybuilding 's popular A subsequent study using samples from wider geographic and ethnolinguistic groups showed that eBSPs, seBSPs, and southwestern BSPs (swBSPs) are genetically closest to Bantu speakers from Zambia (Choudhury et al. 2020). WebCLASS OF 2020 SENIOR PROFILE ADMISSIONS CRITERIA AND PROCESS Eligibility Applications are accepted from 8th grade boys enrolled in parochial, independent, and 2022). (2017), who estimated that admixture between Bantu speakers and eastern African pastoralists occurred 800400 years ago, but are in agreement with 71% Bantu-related ancestry in an ancient Iron Age individual dated to 1,160 years ago from the Rift Valley in Kenya (Prendergast et al. 2010; Fadhlaoui-Zid et al. 2020). For an excellent review of the interactions between BSPs and RHGs, see Patin and Quintana-Murci (2018). Lastly, small amounts of admixture among Sahelian groups have been inferred from genome-wide markers (Fortes-Lima et al. Broadly in agreement with historical records of the transatlantic slave trade, genetic studies of admixed populations from the Americas showed that most of the African ancestry can be traced to WestCentral Africa, for example, similar to the Yoruba or Esan from Nigeria, with a smaller fraction being similar to south-eastern African ancestry, for example, Mbukushu-like from Botswana and/or Luhya-like from Kenya (Patin et al. 2011). Additional details about the deep population structure and the state of ancient DNA research in Africa can be found in reviews by Hollfelder et al. 2019; Micheletti et al. Arabic-speaking populations from Central and Eastern Sahel form an east-to-west genetic cline due to varying amounts of Middle Easternrelated and East Africanrelated ancestry (Fortes-Lima et al. 2023). 2018), whereas methods leveraging LD patterns yielded estimates <1 kya (Patin et al. 2015). then you got the germans and eastern europeans who also generally have very good genetics for muscle size. The remaining traditional huntergatherer groups in Africa can be broadly grouped into three major groups: Khoe-San, eastern African huntergatherers (EAHG), and rainforest huntergatherers (RHG). In our study, though only 1.3% of Afrikaner genes came from the Khoe-San, most Afrikaners contained some Khoe-San genes. At K = 2, African-like and European-like ancestry cluster separately, and at K = 3, a Khoe-San component appears. WebSpeak with a Genetic Counselor. 2017). Paleolithic (Old Stone Age)The period of time in human evolution when people initially started using stone tools, extending from 3.3 million years ago (Mya) to 12 kya. Mexican Genetics Study Reveals Huge Variation Furthermore, there is also genetic evidence that admixture has facilitated adaptation to Malaria in Cabo Verde during the past 20 generations, with selection coefficients acting on the DARC locus as high as s = 0.08 (Hamid et al. Additionally, despite more males being deported to the Americas, it has been shown that African contributions to gene pools in the Americas were likely female-biased, whereas European contributions were likely male-biased (Mathias et al. A Snakemake (Mlder et al. Despite the evidence for archaic admixture, it cannot be ruled out that deep population structure confounds the inference of archaic ghost introgression in Africa (Ragsdale et al. Today, only a few traditional huntergatherer groups remain that live in small communities. How the climate affects the Africans body size. 2009). as we all know, africans rule when it comes to genetics, it gets no better, either in bodybuilding or sports. Sep 2018 - Feb 20201 year 6 months. WebThe genetic history of Egypt reflects its geographical location at the crossroads of several major biocultural areas: North Africa, the Sahara, the Middle East, the Mediterranean and sub-Saharan Africa.A 2017 DNA study found that Ancient Egyptians had a genetic profile similar to that of modern Egyptians and had a high affinity with the population of the (B) Southward migration of Bantu-speaking people through the rainforest to modern-day Angola (ANG) and Zambia (ZMB) before splitting into eBSPs and seBSPs, in concordance with the late-split hypothesis. The first evidence for archaic ghost introgression in Africa was obtained by applying S*an approach that searches for highly divergent haplotypesto African populations (Plagnol and Wall 2006). How East Africans Have Good Genetics for Muscle Building Evolutionary Genetics and Admixture in African Populations 2014; Macholdt et al. Using SpaceMix analyses, Vicente, Jakobsson et al. 2010; Republic of South Africa 2021). West African - Overall ideal genetics for MMA, Football, Basketball, Bodybuilding, Stregnth, 2014; Choudhury et al. 2020a; Lipson et al. 4D) (Henn et al. #DominanceDisciplineDirection. 2017; Swart et al. This example illustrates that admixed African populations are a promising opportunity to better understand ancestry-specific disease risk compared with homogeneous populations (Patterson et al. 3. 2020) or comparing empirical data to simulated data (Durvasula and Sankararaman 2020; Wang, Mathieson, et al. 2017; Hey et al. 2022) as well as mtDNA and Y haplogroups (kov et al. 2017).

As African population genetics research is still in its early stages compared with its European counterpart (Popejoy and Fullerton 2016; Martin et al. 2. 3. Population structure analysis of 97 African and 7 Eurasian populations. In this review, we focus on genetic studies that uncovered extensive archaic, prehistoric, and recent gene flow that has occurred in Africa. ADMIXTURE plots are shown for K = 2 to K = 12. 2017). The Maghrebi component is represented by 15,000-year-old Paleolithic individuals from Taforalt, Morocco, whose ancestry is best modeled as a mix of an early Holocene Middle Eastern (63.5%), that is, Levantine Natufians, and a sub-Saharan component (Van De Loosdrecht et al. Now the East African people usually have more carbs. 2019; Lipson et al. 2020). Note that we tried to refer to populations according to current naming conventions, and when we refer to admixture between specific populations, this does not necessarily imply the mixing of these exact populations, but rather the mixing of genetically similar populations. 1. Many studies of African genetics have historically focused on sub-Saharan populations, as northern African populations grouped separately from sub-Saharan populations and closer to non-African populations in studies of classical genetic markers (Cavalli-Sforza and Piazza 1993). 2016; Norris et al. 2. In addition, cultural and religious practices contributed to the high degree of heterogeneity in ancestral contributions among SAC individuals sampled from different regions of South Africa (de Wit et al. This estimate is broadly consistent with the estimated coalescence times of North African-specific mtDNA lineages (44 21.6 kya for the U6 lineage, 13.0 5.7 kya for the U6a1 lineage, and 13.5 3.7 kya for the U6a* lineage) and Y chromosome haplogroups (1512 kya for E-M78 in most populations and 4430 kya in Tunisian Imazighen) (Fadhlaoui-Zid et al. Code used to generate this figure can be found at GitHub: https://github.com/LachanceLab/AfricanPopulationStructure. (2022), respectively. Thus, this study indicates that admixture of Khoe-San groups with eastern African pastoralists occurred at least 1.2 kya (fig. 2010; Patterson et al. 2012; Arauna et al. (2022) (see supplementary methods and table S1, Supplementary Material online). 2015; Bergstrm et al. The fact East African people have the highest intermuscular fat percentage among all. 2017). These estimates are in slight disagreement with the estimates of Skoglund et al. For these reasons, Africa is commonly accepted as the cradle of humankind (Henn et al. 3. Based on varying amounts of Mota-related and Dinka-related ancestry in ancient individuals from the Democratic Republic of Congo, Uganda, and Botswana, it has been argued that a model with repeated, unidirectional gene flow from east African forager groups and Nilo-Saharanspeaking groups into the early northeastern pastoralist group provides a better fit (Wang et al. 2016; Bergstrm et al. (2017), Hollfelder et al. A individual who possesses a enhanced genotype is well-suited to the sport of bodybuilding. In this review, we provide an overview of our current understanding of how admixturemostly during the last 10,000 yearshas shaped present-day population structure in Africa and how recent genetic studies complement linguistics and archeology in reconstructing the history of African populations. Specifically, Latin American genomes are enriched for African MHC/HLA haplotypes (Zhou et al. For example, a recent study of 180 African huntergatherer genomes from 12 populations discovered 5.3 million novel genetic variants of which 78% are population-specific and of which many are predicted to be functionally relevant (Fan et al. Excellent site you have here.. Its difficult to find excellent writing like yours these days. Altogether, if the current underrepresentation of marginalized groups in genomic research is not corrected, existing inequities are likely to be exacerbated. This gene flow from wBSPs into RHGs was inferred to have occurred 7 kya using models of site-frequency spectra (Hsieh, Veeramah, et al. (A) The stepwise spread of lactose persistence from northeastern Africa into eastern Africa and subsequently into southern Africa. 2018). 2014; Fan et al. WebGenetics matter for pretty much any sport, and this especially applies to strength training. Why do East African men have bigger muscles? East Africans, it seems, is more suitable for hard physical labor than other countries. This gives them remarkable elasticity in their skin, which allows the skin to react to the strain. 2017; Batai et al. For example, the Amahara people have adapted to low barometric pressure and hypoxia in the Ethiopian Highlands over the past 5,000 years. Subsequently, the Mbuti (RHG) diverged 220 10 kya from all other human lineages, forming a second basal lineage (Schlebusch et al. Reddit - Dive into anything (2019), and Fortes-Lima et al. As expected, the Sahara, Red Sea, central African rainforest, and the Kalahari Desert act as ecological barriers. East An intriguing example is EPHB1, an ephrin receptor at sites of osteogenesis. 2020; Chen et al. 2019). 2022). The official Team3DAlpha Reddit. Regulatory DNA appears to be a frequent target of adaptation in African genomes (Quiver and Lachance 2022). Now that we know more about DNA, genes, and health, it is clear that some people are born with a boost in the muscle department. 2022). The genetic basis for elite running performance | British Journal of (D) Repetitive gene flow from the Middle East/Europe and sub-Saharan Africa into Northern African populations. 2020). 2009; Ansari-Pour et al. Despite recent progress, African populations are still dramatically underrepresented in genetic studies, and more studies of African genetic variation and population structure are needed. 2019; Fortes-Lima et al. Similarly, EAHG groups, for example, the click-speaking Hadza and Sandawe in Tanzania and the Chabu in Ethiopia, are traditional foragers, who have practiced a huntergatherer lifestyle until recently or are still practicing it (Bower 1991; Prendergast 2020). 2012; Schlebusch et al. Two admixture events involving a West African group and two different European groups dating to 1.8 kya and 300 years ago have been identified. Zack Synders Axel In Harlem (5-2) on Twitter: "RT @DRXIDAGXD: Nevertheless, when accounting for recent admixture, studying the genetics of the traditional huntergatherer groups in Africa can provide a snapshot of deep population structure due to their long-term population continuity. Ne determines the strength of genetic drift acting on a population. 2. 2019). Possibly, Khoe-San were the only inhabitants of southern Africa for much of its prehistory (Schlebusch et al. One key evolutionary challenge involves physiological responses to extreme conditions, including high-altitude desert environments. By contrast, genetic studies are uniquely equipped to identify large-scale demic movements (e.g., Tishkoff et al. 2014, 2017). 2012). Nevertheless, African huntergatherers have the highest level of genetic diversity of extant populations and represent the most deeply branching human lineages even after accounting for recent admixture (Henn et al. 2016; Lopez et al. (2020). However, many genes that are associated with immune response are highly pleiotropic, for example, major histocompatibility complex (MHC), human leukocyte antigen (HLA) genes, and apolipoprotein L1 (APOL1), complicating attempts to pin down the primary cause of recent adaptations. Whereas the Mbuti and the Biaka have <6% wBSP-related ancestry, the Bezan and the Bongo trace as much as 38.5% and 47.5% to wBSPs, respectively (Patin et al. Something along the line of competition and hard labor work required for early human civilizations that created new tools, fed the population and made a culture all those things require the fitness of people. One key example of this involves tuberculosis, a disease that has particularly severe infections in the SAC population (Chimusa et al. 2022). Genetic studies showed that the spread of Bantu languages, agricultural practices, and iron use 53 kya was accompanied by multiple migration waves of Bantu speakers from western Africa (i.e., current eastern Nigeria and western Cameroon) to other regions in sub-Saharan Africa (Tishkoff et al. - Bodybuilding.com Forums Shop Protein Protein Whey Protein Whey Protein Isolate Weight Gainers Casein Protein Egg Protein The Kx`a-speaking Ju|Hoan and !Xun and the Khoekhoe-speaking Hai||om are representative of the North Khoe-San ancestry component, the Khoekhoe-speaking Nama and Tuu-speaking Khomani and Karretije are representative of the South Khoe-San ancestry component, and all remaining Khoe-San population are representative of the central Khoe-San ancestry component (Montinaro et al. Subsequent studies of genome-wide data that included more Imazighen populations confirmed that most Arab and Imazighen populations are weakly genetically differentiated (Arauna et al. 2014; Rees et al. Given the scope of this review paper, we cannot comprehensively review the evolutionary history of every population. The Western Cape, at the southernmost part of South Africa, harbors one of the most diverse admixed populations, namely, the South African Coloured (SAC) population, which is the largest ethnic group in this region and has its origins slightly >350 ya (de Wit et al. (2017), Crawford et al. 2. 2020). 2015; Mallick et al. 2019; Gouveia et al. Understanding how this population-specific genetic variation influences complex traits is particularly important in the context of polygenic scores. The ability to break down starchy foods also appears to have been a target of selection. Nevertheless, ancient DNA has recently been obtained of 18,000-year-old individuals (Lipson et al. Human population tree. ACTN3 is the stronger geans code in muscle building and this is scientifically proven. (A) Mapping of ADMIXTURE proportions at K = 4, that is, Eurasian-like, West African-like, Khoe-San-like (southern Africa), and East African-like ancestry, on a geographical map using the ordinary Kriging method. Brown shading indicates lower effective migration rates, and blue shading indicates higher migration effective migration rates, with edge weights quantified by log10(w). 2018). The exact admixture timings differ between populations (1.7 kya700 ya), with northern groups showing older dates than southern groups (Sengupta et al. 2022). Because of this, the biomedical field benefits from an in-depth understanding of genomic variation in diverse populations (Rotimi and Jorde 2010). 2020). (Epidermal Abundance) They have a thick outer layer of skin on their overall body. East Africans have different fat percentages compared to Europeans, Americans, and other countries. There Are Some Resones Of Why east african Have Good genetics For bodybuilding. 2020) (fig. Another example of adaptation to extreme conditions are RHG groups, who evolved a short stature (mean adult height <160cm). 2020), a pattern that is consistent with the evolutionary benefits of gene flow. 2019; Wohlers et al. Individuals with shared genetic ancestry tend to be more genetically similar. Thus, the higher genetic diversity and lower LD in African populations reflect historically larger Ne. 2017). 2. Subsequent admixture with European-like ancestry and Native American-like ancestry populations was spatially and temporally complex, leading to varying amounts of recent African-like ancestry in admixed populations in the Americas (Bryc et al. Zane had access to the best gyms in the world whereas Kulbila is lifting pipes strapped with rotten metal. 2012; Schlebusch and Jakobsson 2018; Gopalan et al. 5. [1] Databases [ edit] 2022). This selection has largely occurred during the Holocene, making it a relatively recent phenomenon from an evolutionary perspective. 2017; Sengupta et al. 2020; Lucas-Snchez, Font-Porterias, et al. 2019; Anagnostou et al. Genetic ancestryThe genealogical paths through which an individual inherits DNA from specific ancestors in a reference population. 2014; Macholdt et al. genetic (2016), Arauna et al. Several studies have revealed a sex-biased gene flow in SAC that supports the historical records indicating that almost all mixed marriages were between a male settler and either a free Black female (where the man bought the slave their freedom) or an indigenous Khoe-San female (Patterson et al. 2013). 2015) and allowing to narrow down causal variants (Jallow et al. 2012; Li et al. 2017; Fortes-Lima et al. 2020). East African population has a very low food intake. A study done with east african genetics for bodybuilding shows that when they were sedentary for one month they grew an average of 11% in muscle mass. 2010; Petersen et al. 2010; Daya et al. Web1) Low Bench Press. 2013; Patin et al. Training more diverse scientists and building research capacities on the African continent not only leads to better research but may also help to address the lack of diversity in study cohorts (Hindorff et al. Furthermore, many noteworthy instances of selection in Africa are associated with physiology, diet, or pathogen pressure. It has been argued that this gene flow must have occurred within the last 10 ky after the prehistoric lake Makgadikgadi dried up (Barbieri et al. 2017). No amount of political correctness can obscure the reality that East Africans have a distinct, genetically-endowed body type and physiology. 2020a). The present meta-analysis included 100 populations from 36 As their genetic diversity is still significantly higher after accounting for recent admixture with nonKhoe-San groups, it reflects their historically larger Ne (Kim et al. african genetics bodybuilding Matjuda EN, Engwa GA, Anye SNC, Nkeh-Chungag BN, Goswami N.

These are some genes I saw on here that carry an advantage So it is almost like starting to exercise at around 40 and having enough energy to exercise and still look and feel good in the 70s. 2016). Furthermore, east African pastoralist contributions to Khoe-San groups are lower on X chromosomes than autosomes (Vicente et al. 2011; Ranciaro et al. First, we give a brief overview of genetic variation in Africa and examine deep population structure within Africa, including the evidence of ancient introgression from archaic ghost populations. Bodybuilders work hard to perfect their six-pack abs and other muscles through intense training sessions, but many also have ripped bodies due to their genetics. Selection scans comparing Amhara individuals living at high altitude to individuals living in lowland areas have implicated a number of adaptive loci, including rs10803083, a SNP that is associated with hemoglobin levels (Alkorta-Aranburu et al. Since they never had bad diseases which lead to skin tissue rupturing, their skin is able to repair quickly. ), genetics, testosterone, dating, Psychology, and race & ethnicity. 2006), genetics are in favor of the late-split hypothesis, as eastern BSPs (eBSPs) and south-eastern BSPs (seBSPs) are genetically closer to western BSPs (wBSPs) south of the rainforest (i.e., Angola) than to wBSPs north of the rainforest (Patin et al. Additionally, Sengupta et al. The selective pressure at this locus appears to be of regulatory nature as no nonsynonymous variant was found (Hsieh, Veeramah, et al. 2012) and mitochondrial DNA (mtDNA) (Barbieri et al. Despite the modest FST values, fine-scale population structure of BSPs has recently been emphasized (Semo et al. 2020). They need to maintain their body temperature by keeping warm. 2017; Lopez et al. 2021). 2019; Wall et al. Hammer MF, Woerner AE, Mendez FL, Watkins JC, Wall JD. Ultima Genomics - YourDNA For instance, ancient huntergatherers genomes from Malawi (8,1002,500 BP) and Tanzania (1,400 BP) exhibited two-third and one-third San-related ancestry, respectively, suggesting that the San previously occupied a larger geographic area extending into eastern Africa (Skoglund et al. However, evidence supporting additional admixture events with unknown archaic homininsthe so-called archaic ghost populationswithin Africa is also mounting (Lorente-Galdos et al. 2022).
