DID AFRICAN SLAVES BRING THE Y-CHROMOSOMES R1 CLADES TO THE AMERICAS?

ABSTRACT
Previous studies of the genetic structure of Afro-Americans have observed a considerable presence of European haplotype R1, among Afro-Americans in North America and the Caribbean. Researchers have assumed that these European genetic signals were probably the result of European males mating with Sub-Saharan African (SSA) females during the Atlantic Slave Trade. Even though this is the usual explanation for the presence of European clades carried by Afro-Americans (AA), recent studies show a high frequency of R haplogroup ancestry among SSAs in West Africa. This study illustrates that the existence of Y-chromosome R1a, and R1b (M-269 and V88) among Afro-Americans may be derived from SSAs instead of Europeans.
