I have not seen many genetical studies on Haiti, but i know one Haitian who took a DNA test, i am not sure where, but she came out as 60% African, 10% Native, 30% euro, might be Africanancestry.com or something, i am not sure i need to ask her again. I think quite a few Haitians will have native admixture, although in small amounts, and a few will have high native admixture, higher then 10%. European admixture is probably higher then native admixture in Haiti.
