Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct, and that using it as a proxy for genetic differences among populations is misleading. [1] [2]
Map of Africa and the African diaspora throughout the world. The genetic history of the African diaspora is composed of the overall genetic history of the African diaspora, within regions outside of Africa, such as North America, Central America, the Caribbean, South America, Europe, Asia, and Australia; this includes the genetic histories of African Americans, Afro-Canadians, Afro-Caribbeans ...
Populations in Africa tend to have lower amounts of linkage disequilibrium than do populations outside Africa, partly because of the larger size of human populations in Africa over the course of human history and partly because the number of modern humans who left Africa to colonize the rest of the world appears to have been relatively low.

During the early period of the Holocene, 50% of Sub-Saharan African mitochondrial DNA was introduced into North Africa by West Africans and the other 50% was introduced by East Africans. [90] During the modern period, a greater number of West Africans introduced Sub-Saharan African mitochondrial DNA into North Africa than East Africans. [90]
Haplogroup A is a human Y-chromosome DNA haplogroup, which includes all living human Y chromosomes.Bearers of extant sub-clades of haplogroup A are almost exclusively found in Africa (or among the African diaspora), in contrast with haplogroup BT, bearers of which participated in the Out of Africa migration of early modern humans.
Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs , only a tiny amount are unique to us, making us about 99.9% ...
Y-DNA lineages E-V12 and E-V22 have been associated with a Levantine source (represented by modern Lebanese), while North African haplogroup E-M81 shows an average frequency of 1.53% in the current Sicilian and Southern Italian genetic pool, but the typical Maghrebin core haplotype 13-14-30-24-9-11-13 has been found in only two out of the five ...
Gender, on the other hand, “is the expression of the characteristics that we have associated with what it means to have those genitals,” says Leech. Basically, someone’s gender is their ...
