[Seasonal changes in the resistance of a Drosophila population to low temperatures and their association with fertility].

Abstract excerpt

Significant genetic variation in resistance to cold was detected in samples collected from a natural Drosophila population in spring, summer, and autumn. In the summer sample, phenotypic variation was determined by genetic factors; in the summer and autumn samples, exclusively by environmental factors. Flies collected in spring had the highest longevity at low temperatures. In summer, their longevity at low...
