Differential linkage disequilibria and the gene frequency analysis of Adh and $alpha$Gpdh loci in a natural Drosophila melanogaster population from Northern Anatolia of Turkey

Abstract

Different diseqeulibria at aGpdh and Adh loci were detected between sexes in a natural Drosophila melanogaster population from province of Ordu in Northern Anatolia. The almost identical patterns of gene frequency and the similar magnitudes of genetic distances in both sexes exclude selection as a possible cause for the different disequilibria observed. A sampling effect similar to genetic drift, or an emergent effect of migration is favored in ligth of the presence of a difference in one of the gametic type.
