Detailed explanation-1: -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-2: -Haploid cells contain only one set of Chromosomes (n). Diploid, as the name indicates, contains two sets of chromosomes (2n). Haploid cells are formed by the process of meiosis.

Detailed explanation-3: -In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.

Detailed explanation-4: -During the first meiotic division, the centromeres of the chromosomes do not replicate; therefore the two chromatids of each chromosome remain together duringtelophase. The resulting daughter nuclei thus are haploid (1n) but 2C: they contain the same amount ofDNA as the parent germ cell but half as many chromosomes.

Detailed explanation-5: -The term haploid came from Greek haplous, meaning single. The words haploidic and haploidy are derived words. Their definitions are based on the meaning of haploid. For instance, the word haploidic is used to pertain to a cell or an organism having half of the set of homologous chromosomes.
