the study of how to arrange reproduction within a human population to increase the occurrence of heritable characteristics regarded as desirable. Developed largely by Sir Francis Galton as a method of improving the human race, eugenics was increasingly discredited as unscientific and racially biased during the 20th century, especially after the adoption of its doctrines by the Nazis in order to justify their treatment of Jews, disabled people, and other minority groups.
Eugenics is the practice or support of selecting marrying persons with particular desired genetic characteristics in order to improve the human species. Its goal is to alleviate human suffering by "breeding out" sickness, impairments, and other "undesirable" traits from the human population.
