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 ...
The proportions of various human Y-DNA haplogroups vary significantly from one ethnic or language group to another in Africa. Data in the table below are based on genetic research.
The following articles are lists of human Y-chromosome DNA haplogroups found in populations around the world. Y-DNA haplogroups by ethnic group; Y-DNA haplogroups in populations of Europe; Y-DNA haplogroups in populations of the Caucasus; Y-DNA haplogroups in populations of the Near East; Y-DNA haplogroups in populations of North Africa
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.

Paige said Ancestry.com has fewer than 2,000 African DNA samples in its database, representing only nine African countries and a handful of ethnic groups. 23andMe, she said, has around 4,300 ...
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]
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]
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% ...
