Detailed explanation-1: -Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
Detailed explanation-2: -A haploid cell has only a single set of chromosomes. Most cells in humans are diploid rather than haploid, meaning they have two copies of each chromosome.
Detailed explanation-3: -Sperms and egg cells are haploid and contain one set of chromosomes.
Detailed explanation-4: -Human gametes (egg and sperm cells) are haploid, containing 22 autosomes and one sex chromosome.
Detailed explanation-5: -In the male, the production of mature sperm cells, or spermatogenesis, results in four haploid gametes, whereas, in the female, the production of a mature egg cell, oogenesis, results in just one mature gamete.
