east african genetics bodybuilding

Note that subsequent gene flow can confound these estimates. 2015). 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. 2022). This is one advantage because they have more options of what to eat. Two major migratory routes of Bantu-speaking populations (BSPs) have been hypothesized. In line with the OOA model, many human populations experienced a major decline in Ne coinciding with the OOA migration 7050 thousand years ago (kya) (Bergstrm et al. With the sequencing of genomes of archaic hominins, it has become evident that modern humans interbred with archaic hominins on multiple occasions in Eurasia (Green et al. 3A), with deserts and rainforests acting as major barriers to gene flow (fig. WebDesign, setting, and participants: This post hoc analysis of the SPRINT trial incorporated data from a multicenter study of self-identified Black participants with available West African ancestry proportion, estimated using 106 biallelic autosomal ancestry informative genetic markers. 4C). 2022). 2022; Fan et al. (2017), Scheinfeldt et al. We also see that East Africans have a lot of strong big people (muscle). 2023). 2017; Prendergast et al. 2017; Novkov 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. Most contemporary African groups share some of their ancestries with groups from different geographic regions (fig. 2014). However, Durvasula and Sankararaman (2020) did not find evidence for introgression at the MUC7 locus when they applied a novel statistical method (ArchIE) that identifies introgressed segments based on multiple population genetics statistics to western African genomes. The remaining ancestry can be predominantly assigned as European-like, with minor contributions from Native American groups in some populations (Micheletti et al. 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. 2017; Hollfelder et al. Additionally, putatively selected regions also included genes unrelated to height, such as genes associated with reproduction, thyroid function, and immune traits, among others (Jarvis et al. 5. 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. Henn et al. This difference in muscle mass is due to different genetic structures. 2021; Tallman 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. 2013; Petersen et al. In contrast to seBSPs, swBSPs appear to have reached southern Africa more recently (750 ya), as indicated by more recent admixture of a western African-related source in the Khoisan-speaking Khwe and !Xun from Angola (Busby et al. Because of this, the biomedical field benefits from an in-depth understanding of genomic variation in diverse populations (Rotimi and Jorde 2010). 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). 2009). 2017; Fortes-Lima et al. Their overrepresentation among the worlds best 2016; Ongaro et al. 2020; Micheletti et al. However, most sub-Saharan gene flow was inferred to have occurred more recently during the last 700 years, leading to varying degrees of sub-Saharan ancestry in contemporary North African populations (155%) (Henn et al. It has been shown that genetic and ancestry-related information plays a significant role in accurately determining appropriate dosage (Bress et al. 2020). 4. Roughly around 40%-60% of most aspects of your body are genetically predetermined. 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. By sampling the petrous bone (), we sequenced the genome of a male from Mota Cave (herein referred to as Mota) in the southern Ethiopian highlands, with a mean coverage of 12.5 ().Contamination was Genetic clineA gradual change of allele frequencies over a specified geographic area. 2016; Patin et al. 2018; Van De Loosdrecht et al. 2022). Mystery DNA like 95% of the genes and genomes for humans comes from Africa, and why did it happen. ), genetics, testosterone, dating, Psychology, and race & ethnicity. 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. 2020). 2020). 2015; Busby et al. Such studies have produced large amounts of insightful data which have revealed medically relevant genetic loci and aided the interpretation of the pathogenicity of genetic variants, advancing precision medicine for all populations (Choudhury et al. Nonetheless, African populations are connected via gene flow, which can serve as a potent source of adaptive variation. Consequently, the Bantu expansion extensively contributed to population structure due to differential levels of admixture with and replacement of local huntergatherer groups over the past 3,500 years (Skoglund et al. 2022) as well as mtDNA and Y haplogroups (kov et al. Khoekhoe-speaking populations (e.g., the Nama), who currently practice a pastoralist lifestyle, have a high-frequency lactase persistence (LP) allele that is also found in East African populations (Schlebusch et al. Overall, recent genetic studies highlight the spatially and temporally complex dynamics of the Bantu expansion, with differential levels of admixture among sub-Saharan populations and multiple migration waves. East African genetics at work. 2020; Diallo et al. By contrast, genetic studies are uniquely equipped to identify large-scale demic movements (e.g., Tishkoff et al. 2012; Mallick et al. 2012; Hervella et al. West African - Overall ideal genetics for MMA, Football, Basketball, Bodybuilding, Stregnth, 2019). (2023) were common in their African data set (i.e., frequency >0.05) but rare outside of Africa (i.e., frequency <0.01). 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. (2022), respectively. RHG groups and farmer groups are nearly fixed for different haplotypes, suggesting an incomplete selective sweep. 2022). Sep 2018 - Feb 20201 year 6 months. 2012; Schlebusch et al. Once Explore the latest WebDiscover short videos related to east african genetics bodybuilding on TikTok. 3. Despite what is described here, we have only provided an overview of admixture events in the course of major migratory events, for example, the expansion of Bantu speakers. 2021). (2012), Mallick et al. 2012). 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. 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. Regulatory DNA appears to be a frequent target of adaptation in African genomes (Quiver and Lachance 2022). 2012; Hsieh, Veeramah, et al. 2022; Fan 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. However, it is also possible that this allele has not been detected in ancient samples due to a limited number of surveyed individuals. 2..The secret lies in certain parts of their DNA. 2022). Furthermore, consistent with patterns observed in the Americas (Micheletti et al. 2015; Vicente, Priehodov, et al. 2020). When these East African men lived in the equatorial and tropical areas, they have an extremely high oxygen consumption rate, Which allowed them to store up the oxygen for quicker recovery from a workout. 2013); and EGNL1, a gene that plays a central role in mammalian oxygen homeostasis (Scheinfeldt et al. Interestingly, the pairwise genetic divergences of these three components were found to be similar (i.e., similar fixation index [FST] values), and the divergence time was estimated to be 25 kya (95% CI: 1832 kya) (Montinaro et al. That favors physical and athletic gene variants Increase in the population (group, tribe, clan) you are in is a factor that plays a big role in determining overall fitness. 2010; Petersen et al. 2018). 2014; Macholdt et al. 2021). However, more studies of whole genome sequences are needed for exact dating. 1. Neolithization, Arabization, and sub-Saharan gene flow led to the dilution of this Maghrebi component in North African populations (fig. 2022), it is imperative that ongoing efforts to sequence diverse populations on the African continent need to be expanded. 2022). Using this knowledge, we have envisaged a system wherein all the members in your family have access to a genetic profile built especially to mention what their predisposition towards fitness is so they may tread the right path while at it and do away with the notion that if your parents are fat, youll be fat too. 2009), respectively. 2021). Similar distributions of mtDNA and Y haplogroups were observed from whole genome sequencing data of a small group of SAC males from the Western Cape region (Choudhury et al. There appears to be a genetic cline connecting the eastern African Hadza and southern African Khoe-San, as ancient huntergatherer genomes from eastern Africa show affinities to extant southern African San and EAHG (Pickrell et al. This signal of Neanderthal admixture observed in African genomes is most likely not the result of direct admixture but rather the result of admixture with back-migrating Europeans. Published by Oxford University Press on behalf of Society for Molecular Biology and Evolution. 2020). Third, we highlight how natural selection has shaped patterns of genetic variation across the continent, noting that gene flow provides a potent source of adaptive variation and that selective pressures vary across Africa. An intriguing example is EPHB1, an ephrin receptor at sites of osteogenesis. WebEast African Genetics. 2014; Scheinfeldt et al. 2023). 2023), suggesting that the short stature of RHG evolved through positive selection on several loci. 2020), sub-Saharan gene flow was also likely sex-biased with female-biased sub-Saharan and male-biased Middle Eastern contributions (Arauna et al. Together, these findings suggest that Bantu speakers first migrated South through the rainforest to Angola and subsequently to Zambia before splitting into two groups (fig. The timing of selection for LP appears to differ in Africa as well: Strong selection for LP in Maasai herders appears to have occurred more recently than selection for LP in Europe (Schlebusch et al. Brown shading indicates lower effective migration rates, and blue shading indicates higher migration effective migration rates, with edge weights quantified by log10(w). The high genetic diversity contributes to the poor generalizability of polygenic scores in Africa (Majara et al. Lastly, small amounts of admixture among Sahelian groups have been inferred from genome-wide markers (Fortes-Lima et al. 2018). However, an FDA-approved test to inform the dosage of the anticoagulant warfarin surveys genetic variants that are not as relevant to Africans. Gene flowThe movement of individuals and their genetic material from one population to another population. 2015) and allowing to narrow down causal variants (Jallow et al. Interestingly, the Hadza of Tanzania who have a diet rich in tubers tend to have higher copy numbers of amylase genes than populations with low-starch diets (Perry et al. Nevertheless, different genetic ancestries tend to cluster geographically (fig. 2010; Meyer et al. These are some genes I saw on here that carry an advantage Khoe-San collectively refers to Khoisan-speaking San huntergatherers and Khoekhoe herders, who historically inhabit arid regions in southern Africa. The ability to break down starchy foods also appears to have been a target of selection. Additionally, Sengupta et al. Ive a undertaking that Im just now working on, and Ive been at the look out for such info. 2020). found that the East African LP allele is largely absent from ancient pastoralist individuals from Kenya and Tanzania, indicating that east African pastoralists were lactose intolerant as recently as 31 kya (Prendergast et al. 2019; Gouveia et al. This includes gene flow between different click-speaking Khoe-San populations, the stepwise spread of pastoralism from eastern to southern Africa, multiple migrations of Bantu speakers across the continent, as well as admixture from the Middle East and Europe into the Sahel region and North Africa. Im a 100% East African Somali and wanted to know my genetic potential for bodybuilding. Need 2014; Swart et al. Khoe-San derived maternal lineage L0d had a 68% representation in the SAC group studied, while the M/N Eurasian mtDNA lineages were only represented at low frequencies. 2016; Vicente, Priehodov, et al. However, the distribution of these African ancestries varies between different populations in the Americas, with western/central African-related ancestry being more common in the northern parts, for example, the United States, and south-eastern African-related ancestry being more common in the southern parts, for example, Brazil (Gouveia et al.
