摘　　要：人类Y染色体相对长度 (Y/F值 )在不同种族、不同人群中分布有明显差异 ,其与身高、生殖间的关系存在较大争议。本文通过对 10 6例 (5 3对父子 )福建畲族男性Y/F值及身高的测量 ,揭示了福建畲族男性Y染色体相对长度在家系中具垂直遗传性 ,其大Y出现率为 11.1% ,居中等偏下水平。It is found that the distribution of Human Y chromosome relative length ( Y/F ) is different obviously within different ethnic and population.There are disputations on the relationship of Y/F with height and reproduction.By measuring the Y/F and height of 106 case (53 pairs of fathers and sons) of Fujian she ethnic,we can find that the Y chromosome relative length of Fujian she ethnic has plumb inheritance within pedigree and the appearance rate of long Y is 11.1%,below the medium level.
