Only the father is responsible for determining the sex of the child. Explain with the help of an illustration.
The father (male parent) produces X- and Y-bearing gametes or sperms, whereas the mother (female parent) produces only X-bearing gametes or eggs.
During reproduction, the combination of the X-bearing gamete from the male with one X-bearing gamete from the female results in offspring with genetic constitution XX. The child produced is a female or daughter. This proves that only the father is responsible for determining the sex of the child.
