Afro-American and Native American Shared R1 Y-Chromosomes

There are a number of Y-chromosome Haplogroups shared by mongoloid Native Americas and Afro-Americans.


I can not find any information on V88 among Afro-Americans. But I have found information on the frequency of haplogroup R among Afro-Americans.

Haplogroup E-P1 is called E1b1a1 .In the Hammer et al (2006) study while 63% of Afro-Americans carry this haplogroup,1.3% Native Americans carry the same haplogroup.

The second most frequent Y-chromosome among Afro-Americans is R1b. In the Vallone and Butler (2004) study AAs carried around 0.3% R-M207, and 23% R1b.

Miller et al (2006) did a detailed study of Afro-American and Native American Y-Chromosome. Miller et al (2006) revealed that NA and AAs share many R haplogroups including R-M17 and R-M207. It is interesting to note that in relation to R-M269, that 21% carried this haplogroup, while 17.0 of AAs carried the same haplogroup. This is interesting because there is very little statistical difference between 17% and 21%.
