It will then be important to understand the biomedical implications of this yet undiscovered genetic variation and population structure in Africa, to reduce health inequities between populations of African and European ancestry as genetics finds its way into clinical applications. (2016), Arauna et al. The fact East African people have the highest intermuscular fat percentage among all. Consistent with the age of the Taforalt individuals, it was estimated that the Maghrebi component diverged from the Middle Eastern ancestral component 3818 kya, indicating back-to-Africa gene flow prior to the Holocene (>12 kya; fig. For these reasons, studying more granular population structure in Africa, including potentially adapted genes, may increase our understanding of the genetics of complex traits (Chaichoompu et al. 2013; Johnson et al. Given the high genetic affinity of a pastoralist individual who lived 4000 years ago in northern Sudan with ancient individuals from Kenya and Tanzania, it has been argued that this initial dispersal of northeastern pastoralists into East Africa occurred rapidly (Wang et al. However, studies of uniparental markers revealed 1) genetic heterogeneity among North African populations with a west-to-east cline of mtDNA and Y chromosomal haplogroup frequencies, 2) a lack of differentiation between Arabs and Imazighen (Berbers), 3) preliminary evidence for extensive admixture of populations with European-related, Middle Easternrelated, and sub-Saharan Africanrelated ancestry, and 4) an autochthonous North African component (Haak et al. 2022). East African population has a very low food intake. Some of these individuals are located closer to ancient and present-day central African RHG in principal component space (Lipson et al. Genetic counselors are certified professionals who help patients understand the results of genetic testing. 2021). 2012) and mitochondrial DNA (mtDNA) (Barbieri et al. 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. 2011), although models involving eastern Africa and/or multiple geographic regions are also debated (Henn et al. Interestingly, the specific adaptive mutations seen in the Ethiopian Highlands differ from what has been observed in the Tibetan Plateau and the Andean Altiplano. Lorente-Galdos et al. IntrogressionThe interbreeding of individuals from two or more populations that were isolated for a long evolutionary time but are not yet reproductively isolated. A greater understanding of the genetic architecture can help explain differences in disease risk between populations. The amount of gene flow from wBSPs into individual RHG groups varied. How the climate affects the Africans body size. 2012; Arauna et al. For instance, Ragsdale et al. Nevertheless, different genetic ancestries tend to cluster geographically (fig. Arid desert environments also present an evolutionary challenge in Africa. ADMIXTURE plots are shown for K = 2 to K = 12. 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. (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. 2018), and African population history is of exceptional interest to human evolution. 2020). Here, we In this 2010; Meyer et al. 2012). 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. 2023). For a detailed review of the spread of lactase persistence in Africa, see Campbell and Ranciaro (2021). READ THE RULES BEFORE POSTING. Approximately 5,000-year-old Early Neolithic individuals from Ifri nAmr or Moussa, Morocco, show high genetic affinity to the Taforalt individuals, suggesting population continuity between the Paleolithic and Early Neolithic (Fregel et al. 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. 2020). 2012). 2. First, in northeastern Africa, admixture between a population related to contemporary Nilo-Saharan speakers (e.g., the Dinka or Nuer) and a population related to modern groups from northern Africa or the Levant created a group of early northeastern pastoralists. This group then migrated to eastern Africa and admixed with local foragers 4 kya, receiving 20% ancestry from a group related to a 4,500-year-old ancient individual from the Mota cave in Ethiopia that is genetically similar to the isolated, Afro-Asiaticspeaking Aari (Gallego Llorente et al. WebGenetics matter for pretty much any sport, and this especially applies to strength training. 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. The early-split hypothesis suggests that BSPs split at an early stage north of the rainforest, with one group then moving directly South through the rainforest, whereas the other migrated East, north of the rainforest, toward the Great African Lakes. Its bad genetics, my hormones do now allow me. Chen L, Wolf AB, Fu W, Li L, Akey JM. 2022) as well as mtDNA and Y haplogroups (kov et al. 2021). Through this admixture event, the Fulani likely received a European LP variant 13910*T (rs4988235) in the LCT gene region that was then positively selected, reaching frequencies between 18% and 60% in Fulani groups (Lokki et al. Curious about your test results? 2014; Macholdt et al. 2019), there is evidence of modest admixture between the three Khoe-Sanrelated ancestry components. Regulatory DNA appears to be a frequent target of adaptation in African genomes (Quiver and Lachance 2022). This study found that Tunisian Imazighen trace all their ancestry to an autochthonous North Africanthe so-called Maghrebiancestral component, whereas all Arab populations also have European-related, Middle Easternrelated, and/or sub-Saharanrelated ancestry (Henn et al. 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. 2022). 2021). This is of biomedical relevance (see below), and it also enables improved fine-mapping of causal variants in genome-wide association studies (GWAS) because casual variants are tagged by fewer other variants (Auton et al. At the same time, however, it must be ensured that ethical guidelines and standards are obeyed to avoid unintended group harm. 2020) (fig. 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). However, this may also be the result of a strong population bottleneck (Fortes-Lima et al. In contrast, there was a significant Eurasian paternal contribution (71.4%) defined by haplogroups R/I/G/N/O/J in the same group, and the Western European R1b haplogroup was prevalent at 44.4%. Fine-mappingThe processes of refining the location of trait-associated variants in the genomic region of interest to identify likely causal variants based on association statistics and linkage disequilibrium patterns. 2020). Sep 2018 - Feb 20201 year 6 months. 4. 2021; Tallman et al. Scan this QR code to download the app now. A little less than 1% of Afrikaner genes have an East Asian (Chinese or Japanese) origin. Human population tree. Subsequently, the Mbuti (RHG) diverged 220 10 kya from all other human lineages, forming a second basal lineage (Schlebusch et al. Furthermore, uniparental markers and X chromosomal and autosomal data suggest male-biased seBSPs contributions and female-biased Khoe-San contributions (Baji et al. 2021). Similarly to phylolinguistics (e.g., Rexov et al. 2011; Pennarun et al. HaplotypeA set of linked genetic variants that are coinherited. The design of this figure was inspired by Schlebusch et al. However, the choice of reference populations for multiway admixed populations may be sensitive and critical in biomedical research (Chimusa et al. (2017), Hollfelder et al. Altogether, this suggests that North Africa has a deep history of continuous human migration and admixture. East Africa is a strategic region to study human genetic diversity due to the presence of ethnically, linguistically, and geographically diverse populations. 2020; Matjuda et al. 2020). 2017; Vicente, Jakobsson et al. 2022). A individual who possesses a enhanced genotype is well-suited to the sport of bodybuilding. 3.

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. Once 2014). Links to all data sources can be found in supplementary table S1, Supplementary Material online. Although these populations are traditional foragers, some Khoe-San groups have recently adopted (agro-)pastoralist lifestyle. 2019). Explore the latest 2012; Hsieh, Veeramah, et al. 2019; Scheinfeldt et al. Lastly, small amounts of admixture among Sahelian groups have been inferred from genome-wide markers (Fortes-Lima et al. Choudhury A, Sengupta D, Ramsay M, Schlebusch C. Coelho M, Sequeira F, Luiselli D, Beleza S, Rocha J. Hamid I, Korunes KL, Beleza S, Goldberg A. Additionally, the Naro (central) showed evidence of admixture with the Ju|Hoan (northern) and another population characterized by the Central Khoe-San component (e.g., Taa or |Gui). (2021) found that fine-scale genetic substructure among seBSPs in South Africa correlates well with geography and linguistics and persists even after accounting for differential levels of Khoe-San admixture. WebEast African Genetics. 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. One key example of this involves tuberculosis, a disease that has particularly severe infections in the SAC population (Chimusa et al. A direct link between Afro-Asiaticspeaking eastern African (i.e., Amhara- or Oromo-related ancestry) and southern African pastoralists has been established by showing that a 1,200-year-old individual from southern Africa, who has genetic similarities with modern Khoekhoe-speaking pastoralist groups (e.g., the Nama), traces 40% of their ancestry to a Eurasian admixed group related to a 3,100-year-old pastoralist individual from Luxmanda, Tanzania (Skoglund et al. 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). 2021), indicating that male-biased admixture occurred. 1. 2017; Batai et al. 2020) found that models which include archaic admixture in Africa consistently describe the data better than models that do not include archaic admixture. School of Biological Sciences, Georgia Institute of Technology. 3. 2022). 2020a). 2017; Vicente, Jakobsson, et al. 2014). Genetic ancestryThe genealogical paths through which an individual inherits DNA from specific ancestors in a reference population. Thus, the higher genetic diversity and lower LD in African populations reflect historically larger Ne. The first question was What is the reason behind this? Finally, we explore the biomedical implications of population structure in Africa on health and disease and call for more ethically conducted studies of genetic variation in Africa. East Africans have different fat percentages compared to Europeans, Americans, and other countries. In contrast, the late-split hypothesis states that BSPs first migrated South through the rainforest before splitting into two groups, with one moving further South and the other one migrating East toward the Great African Lakes. 2012; Choudhury et al. 2012; Mallick et al. Aaron Pfennig, Lindsay N Petersen, Paidamoyo Kachambwa, Joseph Lachance, Evolutionary Genetics and Admixture in African Populations, Genome Biology and Evolution, Volume 15, Issue 4, April 2023, evad054, https://doi.org/10.1093/gbe/evad054. (2021). Take care!! 2015). 2021). 5. Limited sex-biased gene flow between the Fulani (and/or other sub-Saharan populations) and Arab nomadic pastoralists has been suggested, as more mtDNA than Y chromosomal haplogroup sharing was observed between the two groups, with most shared haplogroups being of sub-Saharan origin (kov et al. Webhello guys, ive often wondered about different races and their ability to gain muscle. Hollfelder N, Breton G, Sjdin P, Jakobsson M. Karlsson EK, Kwiatkowski DP, Sabeti PC. 2017). Additionally, African populations exhibit a faster decay of LD, leading to shorter haplotypes (Auton et al. Lastly, it is also imperative that the same ethical rigor applied to studying living participants needs to be extended to ancient DNA (Gibbon 2020). During this time, slaves were trade by the Dutch East India Company from East Africa, Madagascar and surrounding islands, India, and Indonesia, leading to settlerslave admixture, including indigenous Khoe-San people (de Wit et al. 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
