What are X and Y chromosomes?

 Q:   Ask a Question about What are X and Y chromosomes?       
The 23rd pair of genes determines the sex of a baby. These are X and Y chromosomes. A woman has two X chromosomes, while a man has one X and one Y chromosome. When the chromosomes join together in fertilization, if the sperm contains an X chromosome, it will combine with the X chromosome of the female to produce XX - a girl. If the sperm contributes the Y chromosome, the baby will have one X and one Y chromosome and will be XY - a boy.
