Detailed explanation-1: -Definition. 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 ). Autosomes are numbered roughly in relation to their sizes.

Detailed explanation-2: -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. Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size.

Detailed explanation-3: -You receive half of those from your mother, and the other half from your father. Out of all of these chromosomes, 2 are sex chromosomes (XY or XX) and the other 44 are autosomes. Sex chromosomes are the chromosome in a cell that determine gender. Humans have two sex chromosomes.

Detailed explanation-4: -These are sex chromosomes because they differ between the sexes. In humans, males have one of each while females have two X chromosomes. Autosomes are those chromosomes present in the same number in males and females, while sex chromosomes are those that are not.
