Law of homologous series in hereditary variability and molecular homology of genes

The author considers the most important N.I. Vavilov's generalization in genetics - the low of homologous series in hereditary variability in application to modern investigations in molecular evolution of genes and genomes. The high genes homology in related species and also their regulatory elements was confirmed by comparative analysis of amino acid and nucleotide sequences. The N.I. Vavilov's law of homologous series and modern methodical technologies permit on the basis of classical genetics in combination with molecular one to reveal in full measure the potential of variability of plant genetic resources which is contained in germplasma of seeds keeping in gene banks.
