By means of starch gel electrophoresis and specific staining, molecular forms of aspartate aminotransferase and soluble esterases have been investigated in liver extracts of individuals from a population of Zenaida auriculata. Four alleles at the locus corresponding to soluble or cytoplasmic aspartate aminotransferase have been demonstrated. Distribution of phenotypes in the population is in perfect agreement with that expected according to the Hardy - Weinberg law. A large incidence of variants of two fractions of esterases has been found. This variability is, with all probability, genetically determined. The importance of this type of studies to assess genetic structure and dynamics of animal population is emphasized.
