| Abstract: | Results of the scientific research of genetic mechanisms of ontogenetic and phylogenetic adaptation in the department of genetics and molecular biology of the Odessa national university (ONU) are summarized. The new concept of genetic adaptation and adaptive heterosis is proposed. The evidence are presented that not only selection of selectively valuable alleles of the structural genes of enzymes, but also of gene-modifiers of the gene products are involved in the adaptation of D. melanogaster populations to environmental conditions. As a result, the sets of coadaptation alleles--adaptation complexes of genes (ACG), which are specific to the selective factors, are formed in persons of the population. |
