Haplogroup R (mt DNA)
In human mitochondrial genetics, haplogroup R is a very extended mitochondrial DNA (mtDNA) haplogroup and is the most common macro-haplogroup in West Eurasia.
Haplogroup R is a descendant of macro-haplogroup N. Among its descendant haplogroups are B, U (and thus K), F, R0 (and thus HV, H, and V), and the ancestral haplogroup of J and T.
