Dysgenics (also known as cacogenics) is the study of factors producing the accumulation and perpetuation of defective or disadvantageous genes and traits in offspring of a particular population or species. Dysgenic mutations have been studied in animals such as the mouse and the fruit fly. The term dysgenics was first used as an antonym of eugenics — the social philosophy of improving human hereditary qualities by social programs and government intervention.
