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: -Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.

Detailed explanation-3: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-4: -Gametes are haploid cells. This means they contain only half the number of chromosomes found in other cells of the organism. Gametes are produced by a type of cell division called meiosis.

Detailed explanation-5: -*except sperm cells and egg cells in the ovaries which are “haploid” and have 23 chromosomes (with the 23rd being an X in the eggs, and either an X or a Y in the sperm), and not 46 “diploid” like other cells.
