The natural Drosophila population is genetical heterogeneity on resudial variability of the quantitative morphological traits. On the meristic traits high variability in summer was observe, low – in spring and autumn on the morphometric ones – high in spring and summer and low in autumn. Obtaining seasonal dynamics of the resudial variability put by selection on genotypes, which determining high and low variability. The influence on different types of variability by genetical and environmental factors was discussed.
