性别对智力迟钝风险的影响。

Behav Genet. 1979 Jul;9(4):289-95. doi: 10.1007/BF01068207.

Risks of mental retardation were computed separately for the relatives of male and female probands. When compared, the risks for the relatives of females were always significantly higher than the risks for the relatives of males. These findings are consistent with the hypothesis of a differential genetic loading for males and females.

分别计算了男性和女性先证者亲属智力迟钝的风险。经比较，女性亲属的风险总是显著高于男性亲属的风险。这些发现与男性和女性基因负荷不同的假设相一致。
