title: Distinct electrophoretic polymorphism pattern at alcohol dehydrogenase (Adh) locus of Drosophila melanogaster natural populations from Turkey.
abstract: Small number of Drosophila melanogaster populations from two distinct geographical regions, Central Anatolia and Black Sea, of Turkey were studied. Populations sampled were electrophoresed for a single locus, alcohol dehydrogenase (Adh) to assess population differentiation. Both the magnitude of genetic differentiation levels and the population structure based on hierarchical F-statistics allow populations to be grouped on two genetically divergent area, Central Anatolian and Black Sea. One ecological correlate, average yearly maximum rainfal. Ryear, seems to track this Adh genetic variation pattern. The study also shows that a typical pattern of geographical Adh polymorphism can emerge with a handfull of populations sampled across a relatively small distance.
