Summary Introduction
Introduction: Female mammal’s somatic cells consist of two X chromosomes that they inherit from their parents. Those two chromosomes are tightly condensed and thereby one of them will get inactivated. This condensed form of X chromosome is called as Barr body and the process of formation of Barr body is called as X chromosome inactivation. This is a normal process carried out in the body of female mammals to equalize the expression of the sex cells.

Yes, because any change to the DNA is passed on to the offspring b. Maybe. Sex cells only use half of the body's genetic code. It might get the copy of a gene that wasn't mutated. c. No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring d. Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on. 17 A cbe io four 4hon ito bo ug moto JWhioh hDo of mutation would thisarrow_forward
