Eugenics is a set of beliefs and practices aimed at improving the human population through controlled breeding. It includes “negative” eugenics (discouraging or limiting the procreation of people considered to have undesirable characteristics and genes) and “positive” eugenics (encouraging the procreation of people considered to have desirable characteristics and genes).
