Detailed explanation-1: -Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.

Detailed explanation-2: -Human gametes are haploid(n) as they are formed by meiosis during the process of gametogenesis. Haploid gametes lead to the fusion of male and female gametes, by which a diploid zygote is formed and the number of chromosomes remains the same in the progeny.

Detailed explanation-3: -Gametes are formed independently either from diploid or haploid parents. Gametes are always haploid.

Detailed explanation-4: -This is because when the male and female gametes merge during fertilisation, they produce a diploid cell or zygote with two pairs of chromosomes. The male chromosomes are on one side, while the female chromosomes are on the other.

Detailed explanation-5: -In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes.
