Two independent variants of the APOL1 gene found in African haplotypes carrying signatures of natural selection have been shown to confer protection against the acute version of sleeping sickness caused by T. b. rhodesiense, while at the same time increasing risk of kidney disease when inherited from both parents.
The archaeogenetics of the Near East involves the study of DNA or ancient DNA, identifying haplogroups and haplotypes of ancient skeletal remains from both Y-DNA, and mtDNA and other autosomal DNA for populations of the Ancient Near East (i.e., the modern Middle East including Egypt, Iran (Persia), Iraq (Mesopotamia), the Levant, Turkey (Anatolia), Arabia, Northern Africa, etc.
The Turkish G2b haplotype, and 5 of 6 other almost certain G2b Armenian haplotypes have ancestors from a small region in Kars Province of Turkey near the Medieval capitals of Armenia.
In this case illustrated above with table and graphic, Joseph Felsenstein`s methods for making coalescence statistically independent comparisons using 21 familiar markers haplotypes shows a well shaped, defined, and geographically distributed Kohanim Tree.
