Frequency and character of the distribution of acrocentric chromosome associations are determined in 40 phenotypically healthy native inhabitants of the Latvian SSR (20 males and 20 females). The ability to associations is the lowest for chromosomes 15 and 22 and the highest for chromosomes 21, 14 and 13. It is found that a tendency to associations between chromosomes 21-21 (P less than 0.05) and 13-21 (P less than 0.01) is not of an accidental character.
对40名拉脱维亚苏维埃社会主义共和国（Latvian SSR）表型健康的本地居民（20名男性和20名女性）确定了近端着丝粒染色体联合分布的频率和特征。染色体15和22的联合能力最低，而染色体21、14和13的联合能力最高。发现21 - 21染色体之间（P小于0.05）和13 - 21染色体之间（P小于0.01）的联合倾向并非偶然。
