Erythrocyte glyoxalase I polymorphism in the owl monkey, Aotus

Three erythrocyte glyoxalase I phenotypes were observed in a sample of 235 karyotypically defined New World owl monkeys, Aotus. The selective distribution of glyoxalase I allele (GLO1, GLO2) is related to the karyotype of each animal. Owl monkeys with a karyotype VI had an equal distribution of GLO1 and GLO2 genes in the population. Aotus with karyotype II, III, IV, or V had, exclusively, the GLO2 allele (expressed as the fast electrophoretic phenotype), in contrast with monkeys with karyotype I or VII, which had only the GLO1 allele (expressed as the slow electrophoretic phenotype).
