Genetic variation of aldehyde dehydrogenase in primates

Genetic variation of aldehyde dehydrogenase has been demonstrated in catarrhine primates. The results are in accordance with the formal genetic interpretation: three alleles, AldDH1, AldDH2, AldDH3, at the gene locus AldDH. Obviously, the allele AldDH1 has undergone fixation in Homo and Hylobates, the allele AldDH2 in Macaca and Papio, and the allele AldDH3 in Cercopithecus.
