Question

Explain how, sex is determined in human babies.

In humans, sex is determined at the time of fertilisation. If the father contributes X chromosome during fertilisation through his sperm, then the baby born will be a girl. On the other hand, if chromosome Y is contributed through his sperm, then the newborn will be a boy.
