Detailed explanation-1: -In this situation, each sex cell is a gamete. The gametes of human cells are haploid, from the Greek haplos, meaning “single.” This term implies that each gamete contains half of the 46 chromosomes-23 chromosomes in humans.
Detailed explanation-2: -Haploid refers to the presence of a single set of chromosomes in an organism’s cells. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.
Detailed explanation-3: -These gametes unite together to form a zygote. If both the gametes were diploid, the zygote will have double the number of chromosomes of somatic cells, which in turn results in an abnormal organism. Thus, gametes have a haploid number of chromosomes.
