Abstract

Regional and age-related peculiarities of chromosomal polymorphism are established as a result of studies in C-band heteromorphism of chromosomes 1, 9 and 16 in the long-lived subjects, their relatives and population groups of the Abkhaz and Ukrainian Republics. Heteromorphism frequencies of chromosomes 1 and 9 homologs are higher in the Abkhaz as compared with the Ukrainian Republic. Age-related differences as to the degree of expression of chromosome 9 C-band heteromorphism are found: in the Abkhaz Province the frequency of variants with a high heteromorphism degree increases with age, while in the Ukrainian one--with a low heteromorphism degree.
