Detailed explanation-1: -The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23. Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells.

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

Detailed explanation-3: -The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).

Detailed explanation-4: -Which Cells are Haploid? Gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

Detailed explanation-5: -During meiosis, the ploidy is reduced from diploid (2n) to haploid (1n) in production of eggs and sperm. With the successful union of egg and sperm, the normal diploid (2n) complement of chromosomes is restored.
