Genetic polymorphisms of blood proteins in the troops of Japanese macaques,Macaca fuscata: III. Erythrocyte carbonic anhydrase polymorphism inMacaca fuscata

In order to clarify the genetic relationships between troops of Japanese macaques, the authors have been looking for the genetic variation of blood proteins by electrophoretical technique. In this work the genetic variants of erythrocyte carbonic anhydrase isozymes of 1273 blood samples from 34 troops of this species were examined. The genetic polymorphisms were observed in several troops. The variable troops of CA I were Fukushima, Takasakiyama, Kohchi, Shimane, Shodoshima I, K, and T, Kashima, Kawara, Takasakiyama A, B, and C, and Tomogashima. The variant allele found in these troops is onlyd ₂ allele, which was probably identical with that reported byTashian et al. (1971). The frequencies ofd ₂ allele in the Shodoshima and Kashima troops were very high, and this phenomenon was interpreted as being a result of the founder effect and the random fluctuation of gene frequencies in these troops.
