Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Genes carry the instructions to make proteins, which do much of the work in our cells. Because gene names can be long, genes are also assigned symbols, which are short combinations of letters (and sometimes numbers) that represent an abbreviated version of the gene name. Cells work together to form organs, such as the heart, liver, and skin. Genes are the basic unit of heredity. A gene is the basic physical and functional unit of heredity.
