After boys only, can I give birth to a girl?

Much as literally the sex of the offspring is determined by a man who has sex inheritance chromosomes XY, a woman (XX) is also important in determining the sex of the offspring. COURTESY PHOTO

I strayed and got a baby girl who is now four years old. However, all my children at home are boys. There is a slight resemblance to me but could she be mine? Kasoma

Dear Kasoma,
Many fathers have ended up with a number of children from their spouses or concubines while seeking out a child of a particular gender.
Some couples believe trying with more than one woman will finally gift them their preferred gender, while others thinking their wives are to blame have experimented with concubines. Although some get the gender of their choice, others still get the same one as from their wives.
Much as literally the sex of the offspring is determined by a man who has sex inheritance chromosomes XY, a woman (XX) is also important in determining the sex of the offspring. If the man’s X chromosome fertilises a woman’s X chromosome egg, a girl will result and if a man’s Y chromosome sperm fertilises the woman’s X chromosome egg, a boy results. But inheritance is not just about supply of this or the other chromosome because many factors both in the mother and father may be involved in determination of which sperm fertilises the egg.
Today the commonest DNA tests in our laboratories are done for paternity tests and therefore you do not have to get embarrassed doing the same tests. Resembling a bit when you have paternity doubts is not good enough in determining that you are the father or not.
