I dont do Biology and whatever you read from now on is due to the knowledge I got from the Discovery Channel ;)

I know that the eggs of a woman have only an X chromosome. Its the male sperm that provides the other chromosome whether it be X or Y.

So in short, a stand alone egg has only an X chromosome and a stand alone male Sperm has either an X or a Y.

Good job Ari..........you know many things for someone who do not do biology.

Indeed the egg is a gamete and it carries only one sex chromosome. In all it will have the number of chromosomes that is only 23.
