genetic variation as a test of natural selection.allozymic variation encoded by 26 loci was analyzed electrophoretically in 507 specimens representing 12 populations of green toads, bufo viridis, in israel and the vis adriatic island. genetic variation in bufo viridis is higher than in any vertebrate yet studied. mean heterozygosity per locus per individual (h) is 0.133 (range, 0.105 to 0.159). h is higher in central populations as compared with isolates, and varies among four major protein classes, being highest in transferases and hydrolases ...19751056019
