Intraspecific differentiation of Rana japonica was examined by starch-gel electrophoretic analyses of 15 enzymes and three blood proteins in 505 frogs from 25 populations in Japan. These enzymes and blood proteins were controlled by genes at 25 loci, where 4.6 phenotypes were produced by 3.0 alleles on the average. The fixation indexes (Fst) coined by WRIGHT (1978) were calculated. Of the 25 loci analyzed, the AK and MDH-A loci were zero in Fst, while the Pep-A and Hb-II loci were very high in Fst, being 0.722 and 0.781,respectively. The other 21 loci were 0.020∿0.490 in Fst. The mean proportions of polymorphic loci in each of the 25 populations ranged from ...
