The mtDNA study of ethnic people from South Africa shows substantial African genetic mtDNA contribution in both the Cape Malay and South African Indians. mtDNA of Cape Malay shows 10% African mtDNA contribution in their gene pool including 20% (1 in 5) of South African Indians; there appears to be no African Y-DNA contribution detected but this could be due to the fact that the sample size was small. mtDNA study also revealed that about 1 in 10 South African Black people have mtDNA lineages derived from Eurasian (3.0%) and Asian of Indian origins (7.1%).
