what genetics
Font Size. Genetics is the study of how traits such as hair color, eye color, and risk for disease are passed (âinheritedâ) from parents to their children. Genetics influence how these inherited traits can be different from person to person.
Genetics is the science of the way traits are passed from parent to offspring. For all forms of life, continuity of the species depends upon the genetic code being passed from parent to offspring. Evolution by natural selection is dependent on traits being heritable.
