Genetics is the science of heredity. The discipline has a rich history and involves investigations or molecules, cells, organisms, and populations, using many different experimental approaches. Not only does genetic information play a significant role during evolution, its expression influences the functioning of individuals at all levels. Genetics thus unifies the study of biology and has had a profound impact on human affairs.
