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 bands with fluorescence levels 4 and 5. There was a total of 351 polymorphic Q bands, 0-7 per individual, with a mean of 3.0 in the population. No differences between sexes were observed in the frequency of Q bands. The observed homo- and heteromorph frequencies proved to be in complete agreement with those predicted by the law of Hardy-Weinberg. Chromosome 3 with pericentric inversion of the Q-heterochromatin band was found in two (1.7%) of the 116 subjects. The following questions were examined: (1) the possible selective value of chromosomal Q-heterochromatin material in the adaptation of human populations to extreme environmental factors, in particular to the desert climate; (2) intraracial heterogeneity in Europoids of Eurasia; (3) the taxonomic value of Q polymorphism in ethnic anthropology.
对116名土库曼人（中亚卡拉库姆沙漠的原住民）进行了染色体Q多态性研究。使用丙基喹吖因芥作为荧光染料。在116名年龄在16至20岁的受试者中，发现109人（94.0%）具有Q多态性变体，而7人（6.0%）在荧光水平4和5时完全没有Q带。总共有351条多态性Q带，每人0至7条，群体平均值为3.0条。在Q带频率上未观察到性别差异。观察到的同型和异型频率与哈迪-温伯格定律预测的频率完全一致。在116名受试者中有两人（1.7%）发现了3号染色体，其Q异染色质带发生了臂间倒位。研究了以下问题：（1）染色体Q异染色质物质在人类群体适应极端环境因素，特别是沙漠气候方面可能的选择价值；（2）欧亚大陆欧罗巴人种内部的种族异质性；（3）Q多态性在民族人类学中的分类价值。
