The term is also used for the complete set of chromosomes in a species or in an individual organism and for a test that detects this complement or measures the number.

In the male, the twenty-third pair consists of one X chromosome and one Y chromosome. A karyotype is a pictorial representation of an individual's chromosomes.

The gametes are formed by a process of cell division called meiosis.
