- Abstract
With 12 alleles at the Est-α locus of Drosophila virilis, 44 genotypes of females heterozygous for a pair of them were constructed, and about 4 × 104 of their F1 progenies per genotype were electrophoretically examined. Eighty-three variants different from both of their parental alleles were obtained from a total of 2·0 × 106 progenies. Statistical analysis suggested most of their variants to be recombinants. And no null or inactive allele, of which frequency is several percent in natural populations, appeared in 11·6 × 104 progenies from females heterozygous for active alleles. These results suggest that the high variation of the Est-α locus in this species is generated by recombinants from female heterozygotes.
