Autosomes

Explanation:

On the basis of their function, chromosomes can be categorized as autosomes or sex chromosomes. Autosomes are the chromosomes that carry the genes for any cellular function except the sex determination of the organism. On the other hand, the genes for sex determination of the organisms are present on the sex chromosomes.

Humans have a total of 23 pairs of chromosomes. Out of these, 22 pairs are autosomes and do not regulate the sex of the organism while one pair is of sex chromosomes.

Human males have one X and one Y chromosome as their sex chromosomes while human females have two copies of X chromosomes as sex chromosomes.
