It basically says that 5% of Sicilian Y chromosome haplotypes are shared with Northwest Africans.

Thats something what is very likely...but does not have to mean that the direct Negrid influx must be that high too.

It basically says that 5% of Sicilian Y chromosome haplotypes are shared with Northwest Africans. This is an excerpt: "Using mtDNA haplotype frequency, Semino et al. [32] estimated that African gene flow in to Sicily ranged between 10 and 34%." I understand that North African is not the same as sub-Saharan, but this estimate seems much higher than previous estimates. |
