Biology Q&A:
What are autosomes? |
Autosomes are chromosomes that contain information (gene
sequences) available to both sexes. These are the chromosomes commonly used in
genetic examples.
Previous question:
What are homologous chromosomes?
Next question:
What are sex chromosomes?
Oxford Dictionary of Biochemistry:
autosome |
any chromosome except the sex chromosomes. Hence the genes carried by the autosomes show autosomal linkage (or autosomal inheritance) according to the assortment of their respective autosomes to gamete cells during meiosis. Humans have 22 pairs of autosomes in addition to a pair of sex chromosomes.

Autosome |
This article is about a type of chromosome. For the ancestral discovery method using autosomal DNA, see Genealogical DNA test#Geographic origin tests.
An autosome is a chromosome that is not a sex chromosome, or allosome; that is to say, there is an equal number of copies of the chromosome in males and females.[1] For example, in humans, there are 22 pairs of autosomes. In addition to autosomes, there are sex chromosomes, to be specific: X and Y. So, humans have 23 pairs of chromosomes.
| Human chromosomes | |
|---|---|
| Female (XX) | Male (XY) |
 |
 |
| There are two copies of each autosome (chromosomes 1-22) in both females and males. The sex chromosomes are different: There are two copies of the X-chromosome in females, but males have a single X-chromosome and a Y-chromosome. | |
