Gametes contain half the number of cells of a normal diploid cell. They can also be called as somatic cells. Gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.
Hence, they are haploids
During the process of fertilisation the two gametes meet to fuse into each other, when this happens one chromosome from the mother's DNA and one chromosome from father's DNA form a pair. Both the gametes have 23 chromosomes each.The 23rd pair of chromosomes is called the sex chromosomes. There are two sex chromosomes - X and Y. The mother's DNA always have 22+ X chromosome and father's have a 22+X or 22+Y chromosomes. If a sperm
with the X chromosome fertilizes the Ovum, the zygote will have a XX combination (baby girl). And it is Y, there is a XY combination (baby boy).
Hence, it is haploid
