广义上说,除了那些位于 Y 染色体上的基因,男女的遗传几乎相同。虽然男性只有一条 X 染色体,但是女性也只有一条 X 染色体得到表达。在女性发育早期,两条 X 染色体中随机地有一条处于休眠状态,从而封锁了这条染色体上的遗传信息。女性 X 染色体休眠的结果是,男性与女性的体细胞均只表达一条X染色体。但是男性同时还表达位于 Y染色体上的基因,因此男性在其一生中使用了更为广泛的基因信息。从这层意义上看,男性在遗传上比女性复杂。同时男性在遗传上也更易出 Broadly speaking, except for those genes located on the Y chromosome, men and women are almost identical in their inheritance. Although men have only one X chromosome, only one X chromosome is expressed in women. In the early stages of female development, one of two X chromosomes is randomly dormant, thus blocking the genetic information on this chromosome. As a result of the female X chromosome dormancy, both male and female somatic cells express only one X chromosome. But men also express genes on the Y chromosome, so men use a wider range of genetic information throughout their lives. In this sense, men are more genetically complex than women. At the same time, men are more genetically easier
