Question

What are the paternal and maternal origins for sex chromosomes of female and male offspring?

Answer 1

Ans:-

in female offspring :-

one X. Chromosome comes from mother

and another X chromosome comes from father.

IN MALE OFFSPRING:-

The X Chromosome comes from maternal side.

and THE Y Chromosome comes from the paternal side.

Human sex is determined by the presence or absence of a Y chromosome with a functional SRY gene. Once the SRY gene is activated, cells create testosterone and anti-müllerian hormone which typically ensures the development of a single, male reproductive system.
