Genetics is the study of how traits such as hair color, eye color, and risk for disease are passed “inherited” from parents to their children. Genetics influence how these inherited traits can be different from person to person. Your genetic information is called your genetic code or “genome.” Your genome is made up of a chemical called deoxyribonucleic acid or “DNA” and is stored in almost every cell in your body. Genetics is an important concept to learn because you can predict different traits from parent to offspring, understand how some traits can benefit or even harm the possible offspring. Predicting different traits can also help scientist with developing more desirable traits within an organism (artificial selection).
