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106例(53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。
Abstract: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.
