X Chromosome May Leave a Mark On Male Fertility

sciencehabit writes "Behind every great man, the saying goes, there's a great woman. And behind every sperm, there may be an X chromosome gene. In humans, the Y chromosome makes men, men, or so researchers have thought: It contains genes that are responsible for sex determination, male development, and male fertility. But now a team has discovered that X—'the female chromosome'—could also play a significant role in maleness. It contains scores of genes that are active only in tissue destined to become sperm. The finding shakes up our ideas about how sex chromosomes influence gender and also suggests that at least some parts of the X chromosome are playing an unexpectedly dynamic role in evolution."

The y just suppresses the female parts.

So the suppression of females by the Y Chromosome is natural, and this is what evolution has intended and achieved, and the general oppression of the women in the society is just a natural extension of what is going on in cellular level. So all the male chauvinistic pigs can now breath a sigh of relief, "we can't help it. we are born this way".
