Detailed explanation-1: -A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total. This is 22 pairs of autosomes and a pair of sex chromosomes. One copy of each chromosome pair came from the individual’s mother and the other from the individual’s father.

Detailed explanation-2: -If an organism has 20 chromosomes, then the number of chromosomes the daughter cells have after mitosis is 20 because when a cell divides by the process of mitosis it produces two clone daughter cells having the same number of chromosomes (20) as the parent cell has.

Detailed explanation-3: -Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. 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: -The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
