Explanation:
Detailed explanation-1: -Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.
Detailed explanation-2: -Gametes are produced through a type of cell division called meiosis and hence are haploid in nature. They carry only one copy of each chromosome and therefore contain only 23 chromosomes.
