autosomal microsatellites

Friday 30 September 2005

Fact

 The microsatellite allelic diversity and the number of unique alleles were highest in sub-Saharan Africans. (14533184)

 Neighbor-joining trees based on genetic distances and principal component analyses separated populations from different continents, and are consistent with an African origin for modern humans. (14533184)

 With biparentally transmitted markers, the microsatellite tree also shows that the San are the first branch of the human tree before the branch leading to all other Africans. (14533184)

 No evidence of a genetic relationship has been shown among the Basques and the Hunzo Burusho. (14533184)

 Genetic relationships, as ascertained by these microsatellites, are dictated primarily by geographic proximity rather than by remote linguistic origin, as assesed by Mantel test. (14533184)
