本研究的目的是探讨Y染色体对47，XYY雄性不同身体和头部尺寸的影响，特别是对其身体比例的影响。对7名成年男性进行了25项人体测量，并与4名男性亲属和42名对照男性进行了比较。在大多数维度47中，XYY男性比正常男性大，差异主要在0.5 ~ 1.5 sd单位之间。当考虑到体型的影响时，研究人员发现，47.5名男性的身体比例与正常男性相似。由此得出结论，在47，xyy雄性中，额外的Y染色体在不影响身体比例的情况下增加了它们的生长。这一发现表明，Y染色体含有通过增加其数量结果来影响生长的基因。这种作用可能是由Y染色体对细胞的直接作用介导的。似乎Y染色体基因也影响了身高和体型的性别差异的发展。
The aim of the study was to investigate the effects of the Y chromosome on different body and head dimensions of 47,XYY males, and especially its effect on their body proportions. From seven adult 47,XYY males 25 anthropometric measurements were recorded and compared with four male relatives and 42 control males. In most dimensions 47,XYY males were larger than the normal males, the difference being mainly between 0.5 and 1.5 S.D. units. The body proportions of 47,XYY males were found to be similar to those of the normal males when the effect of size was allowed for. It is concluded that the extra Y chromosome in 47,XYY males causes an increase in their growth without affecting the body proportions. This finding suggests that the Y chromosome contains gene(s) which affects growth by increasing its quantitative outcome. This effect may be mediated by a direct action of the Y chromosome on the cells. It also may seem that the Y chromosomal gene(s) influence the development of the sex difference in height and body size.
