A normal cell in an adult woman has?
Assoli18 [71]

Answer:

The correct answer will be option-A.

Explanation:

The females carry two X-chromosomes in their cells but one of these X-chromosome gets permanently inactivated during embryonic development.

The X-inactivation is known as lyonization which ensures that only one functional X-chromosome should be present like in males.  This process is a random process and therefore a female can have both the functional X-chromosomes and males can also have a functional X-chromosome.

Thus, option-A is the correct answer.
