Why all chromosomes are in females are x |
|
Answer» Human females are homomorphic, i.e., they have two similar *** 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 *** chromosome which is the X chromosome. Because x inactivation is random in normal female the x chromosome inherited from the mother is active in some cells |
