Summary. Eighteen different primate species have been typed for Gm factors present at the human γ 2b and γ 2c loci. Gm factors are absent in lower primates. The Gm factors, associated with γ 2c molecules, namely, Gm(s), (c 5 ), (b 0 ) evolve first in the Cer‐copithecoidea species. Gm(z) occurs together with Gm(a) on human γ 2b molecules, but in baboon sera Gm(z) occurs in the absence of Gm(a). The simultaneous occurrence of Gm(a) and (z) in the same sera is established in Hominoidea. Gm(b 3 ) is present only in gorillas, orangutans, and chimpanzees, while Gm(b 4 ) and (c 3 ) was detected in chimpanzees. Polymorphism for the factors studied exists only in orangutans and chimpanzees. The data show a close correlation between taxonomic classification and the evolution of Gm factors.
