What is Genetics?

Genetics is the science and study of heredity and how living organisms receive traits from previous generations. A gene is a heredity unit that consists of Deoxyribonucleic acid (DNA) that determines characteristics in organisms. DNA is a nucleic acid that contains genetic instructions. These instructions determine the genetics of a living thing. Genes are passed on from parents to children and so on along the family tree, determining everything from gender, eye color and body stature, to behaviors, disorders and diseases.
