Anthropometric measurements of four 46,XX males are compared with those of their first degree male relatives, control males, and a sample of 47,XXY males. Most dimensions of 46,XX males are smaller than those of normal males. 46,XX males are also shorter and smaller than 47,XXY males. The present results support the earlier suggestion that there is a gene(s) in the Y chromosome with a general size-increasing effect and that the Y chromosome has an active role in the development of sex dimorphism in many body dimensions. These four 46,XX males may possess the Y chromosomal gene which sets the later timing of development in males.
对四名46,XX男性的人体测量数据与其一级男性亲属、对照男性以及一组47,XXY男性的测量数据进行了比较。46,XX男性的大多数身体维度小于正常男性。46,XX男性也比47,XXY男性更矮、更小。目前的结果支持了早期的推测，即Y染色体上存在一个具有普遍体型增大效应的基因，并且Y染色体在许多身体维度的性二态性发育中具有积极作用。这四名46,XX男性可能拥有决定男性发育较晚时间的Y染色体基因。
