Genetics is a science that deals with genes and heredity. Everything about us, from the color of our hair and eyes, to how big our noses are, to susceptibility to certain diseases, is determined by genetics. "The laws of genetics apply even if you refuse to learn them." - Allison Plowden.

About Genetics

Genetics a discipline of biology, is the science of genes, heredity, and variation in living organisms. Genetics deals with the molecular structure and function of genes, gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution, variation and change in populations, such as through Genome-Wide Association Studies. Given that genes are universal to living organisms, genetics can be applied to the study of all living systems, from viruses and bacteria, through plants and domestic animals, to humans (as in medical genetics). The fact that living things inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding.
