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 ).

Detailed explanation-2: -All chromosomes except the sex chromosomes are referred to as autosomes. They exist in pairs in the somatic cells whereas singly in the gametic cells.

Detailed explanation-3: -An autosome is any chromosome that is not a sex chromosome. The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosomal (sex chromosome) pairs, which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA.

Detailed explanation-4: -Autosomes differ from sex chromosomes, which make up the 23rd pair of chromosomes in all normal human cells and come in two forms, called X and Y. Autosomes control the inheritance of all an organism’s characteristics except the sex-linked ones, which are controlled by the sex chromosomes.

Detailed explanation-5: -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.
