The blood types of the Neanderthals

[firetown]

We found that the Siberian Neanderthals, Altai and Chagyrskaya, are both homozygous for a derived Neanderthal variant of the O allele, while the European Neanderthal, Vindija, is a heterozygote for two derived Neanderthal variants, an O variant different from Altai and Chagyrskaya, and a rare cis-AB variant. The Denisovan individual is homozygous for an ancestral variant of the O allele, similar to variants found widely in modern humans.

The Denisova and Altai Neandertal are homozygous for the ancestral “A” variant at position 25629943 on chromosome 1 that determines rhesus type in modern humans. This variant means that both are likely rhesus positive.


As far as I can tell from the informative position that determines
rhesus type in humans, both are homozygous rhesus positive.
