โœฆ Synopsis

C polymorphism of chromosomes 1, 9 and 16 was studied in 447 Mongoloids of Central Asia living under different ecological conditions; two highland (Kirghiz) and three steppe (Kazakh, Mongolian, and Dungan) populations. C band sizes were estimated according to the semiquantitative 5-level method of Patil and Lubs (1977). All the ethnic groups studied showed statistically significant homogeneity in the frequency of C variants. It is suggested that chromosomal C-heterochromatin material has no selective value in the process of human adaptation to extreme high-altitude factors.

Chromosomal Q polymorphism was studied in 116 Turkmen, aboriginals of the Kara-Kum desert of Central Asia. Propylquinacrine mustard was used as fluorochrome. Of the 116 subjects aged 16-20 years, 109 (94.0%) were found to have Q-polymorphic variants, while seven (6.0%) showed complete absence of Q b
