Detailed explanation-1: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

Detailed explanation-2: -Scientists have numbered the chromosome pairs from 1 to 22, with the 23rd pair labeled as X or Y, depending on the structure. The first 22 pairs of chromosomes are called autosomes. The 23rd pair of chromosomes are known as the sex chromosomes, because they decide if you will be born male or female.

Detailed explanation-3: -In humans, the twenty-third pair is the sex chromosomes, while the first 22 pairs are called autosomes.

Detailed explanation-4: -An autosome is one of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (XX or XY).

Detailed explanation-5: -The human body has 23 pairs of chromosomes, out of which 22 pairs are autosomes and 1 pair is sex chromosome.
