Detailed explanation-1: -Human gametes (egg and sperm cells) are haploid, containing 22 autosomes and one sex chromosome.
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.
Detailed explanation-4: -20. If a diploid cell contains 40 chromosomes, then the haploid cell contains 20 number of chromosomes. The haploid cells contain half the number of chromosomes as the diploid cells. Thus, if a diploid cell contains 40 chromosomes, then the haploid cell will contain 20 chromosomes.
