Abstract Plasma amylase obtained from twoMacaca species,M. fascicularis andM. mulatta, was investigated by isoelectric focusing. In contrast to recent works, extensive polymorphism at the amylase loci was detected in both species. It is assumed that unequal crossing over has generated two pancreatic loci. The phylogenetic relationship between the species is recalculated. The average identity value is calculated from data obtained byNozawa et al. (1977),I=0.93. If the polymorphic amylase loci are included the genetic identity decreases by at least 2% (I=0.91), meaning that the divergence time between both species would increase by about 30%. Furthermore, the mean degree of heterozygosity also increases by about 30% to 0.10 and the effective population size is underestimated by at least the same order of magnitude.
