Fatherhood Gene decides Boys Or Girls

The gene, inherited from both a man's parents, comes in one of three variations and affects the number of sperm carrying male or female chromosomes. Men with a version of the gene known as "mm" produce more sperm with the Y chromosome and are likely to have sons. Another variant, known as "mf", produces roughly equally numbers of sperm with the female X and male Y chromosomes.

In this case, a man has a 50/50 chance of having a son or daughter.

The third version, "ff", produces more X sperm and more daughters. Because of the gene, men inherit a tendency to have more sons or daughters from their parents, say scientists. A man with many brothers is more likely to have sons, while a man with many sisters is more likely to have daughters.

This research and other scientific studies are the slap in the faces of those who consider women responsible for kids' gender. The studies are evident but we still have many divorce cases with the allegation that the women cannot give birth to a son. I heard educated men saying that they have married again for the son. What the hell it is? when our people would start thinking logically? Why men are negating this fact? How far they would run from this reality? Is there any thing for that we can nominate men as responsible? There is nothing, I guess.
