Baby Girl or Boy


The male gametes or sperm cells in humans and other mammals are heterogametic and contain one of two types of sex chromosomes. They are either X or Y. The female gametes or eggs however, contain only the X sex chromosome and are homogametic.

The sperm cell determines the sex of an individual in this case.

If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY or male.

Which means that the father’s sperm determines the sex of the baby.

In societies that value males more than females, they usually attribute the inability of having a male heir as the wife’s fault.

Right here, it’s scientifically proven that the husband is the one that determines the sex of the baby.

So, instead of changing or getting a new wife, they should change the husband.
