Detailed explanation-1: -Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs. Human gametes (egg and sperm cells), however, contain a single set of chromosomes and are said to be haploid.
Detailed explanation-2: -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-3: -A cell containing two copies of each chromosome is referred to as a ‘diploid cell’; human somatic cells are diploid: they contain 46 chromosomes, 22 pairs of autosomes and a pair of sex chromosomes.
Detailed explanation-4: -Haploid cells contain only one set of Chromosomes (n). Diploid, as the name indicates, contains two sets of chromosomes (2n).
