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.
