Domestication and N.I. Vavilov’s law of homologous series in hereditary variability

Abstract

Domestication traits in animal and plant species distinguishing them from closely related wild species are discussed. Data are given on what such traits are found not only at the phenotypic level but also in polymorphism of electrophoretic variants of protein groups with a different biochemical function, DNA fragments flanked by inverted short repeats. The assumption that retrovirus infections can participate in the formation of domestication traits is substantiated.
