One chromosome from each pair is inherited from each parent. What is a Gene?DNA are called genes. Each gene provides the cell with different information. Each chromosome is made up of many genes. There are about 100,000 genes found on human chromosomes.

The hereditary information in DNA is stored as a code of four nitrogen bases: Adenine, Guanine, Cytosine, and Thymine.
