[Gene-enzyme alcohol dehydrogenase system and adaptability in Drosophila melanogaster].
As follows from the experiments on the genotypic related populations of Drosophila melanogaster with different frequency of ADH allozymes selection for postponement of ageing and resistance to hypothermia lead to saturation of population with S-allozyme ADH, and genotypic adaptation to ethanol-to increasing of frequency of F-allozyme. It is supposed that genotypic adaptation is realized by selection of specimens with the most favourable alleles of genes. At the same time ontogenetic adaptation is accompanied by biochemical modification of existing allozymes.
