Most human cells contain 23 pairs of chromosomes, for a total of 46 chromosomes. One set of chromosomes is inherited from each parent. Of the 23 pairs of chromosomes, 22 pairs are autosomes, which control traits unrelated to sex, and the remaining pair consists of sex chromosomes (XX or XY). Human chromosomes contain a total of 20,000 to 22,000 genes, the majority of which have two more possible versions, called alleles.

Chromosomes are coiled structures made of DNA and proteins that form during cell division and are encoded with genetic instructions for making RNA and proteins. These instructions are organized into units called genes, which are segments of DNA that code for particular pieces of RNA. The RNA molecules can then act as a blueprint for proteins, or directly help regulate various cellular processes. There may be hundreds or even thousands of genes on a single chromosome.
