Explanation:
1. If a sperm with a Y chromosome fertilizes the egg, the new cell will have an X and a Y chromosome. The X came from the mother's egg and the Y came from the father's sperm. Since the sex chromosome that is made is XY, the cell will grow into a boy baby.
2. If a spermatozoon with an X chromosome fuses with the ovum, the offspring would be a female (46, XX)
3. Individuals having two X chromosomes (XX) are female
4. In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
5. In females, there is a pair of identical sex chromosomes called the X chromosomes. In males, there is a nonidentical pair, consisting of one X and one Y.
