Cacogenic describes something producing bad offspring or inferior stock. It's the polar opposite of eugenic, and relates to a decline in hereditary qualities. Think of it as the opposite of selective breeding for positive traits. If eugenics is about breeding prize-winning horses 🐴, cacogenics is about letting the sickly ones reproduce. It suggests a downward spiral in the genetic health of a population. Thus, cacogenic pertains to a deterioration of desirable traits.
