Question

why do all gamates formed in human females have an X chromosomes​

Answer 1

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.

Answer 2

All gametes which are formed in human females have X-chromosomes because-

• Human females are homogametic in nature which means they have two similar chromosomes .
• During the time of gamete formation in meiosis period X-chromosome enters each gamete.
• And all the gametes possess one X- chromosome .
• Therefore all the gametes formed in human females will have only one type of sex chromosome i.e, X chromosome.
