Question

Why do all gametes formed in human females have an x chromosome ? Explain?

Answer 1

Bcz human females are homozygous that means they have 2 X chromosomes besides autosomes and therefore all gametes have an X chromosome

Answer 2

here is your answer

Human females are homomorphic, i.e., they have two similar sex chromosomes. Hence, during meiosis at the time of gamete formation, one X-chromosome enters each gamete. Hence, all the gametes possess an X- chromosome and the human female is said to be homogametic which means all the gametes produced will have only one type of sex chromosome which is the X chromosome.
