Question

How is sex determined of an unborn baby?

Answer 1

Through the aid of chromosomes...

Explanation:

We have the `X` and `Y` chromosomes..

A woman has `XX` chromosomes, while a man has `XY` chromosomes

During copulation a woman must always release `X` chromosome, while a man can either release `X` or``Y# chromosome..

Therefore, if a man release `X` chromosome, the child will be female having `XX` chromosomes..

But if he releases `Y` chromosome, the child will be male having `XY` chromosomes..

Sumarry

Female Sex is denoted with `XX` chromosomes..

Male Sex is denoted with `XY` chromosomes..

Hope this helps!
