inbreed
Breed within family
To inbreed is to breed from closely related individuals—siblings, parents and offspring, or near cousins.
Animal breeders inbreed deliberately to fix desired traits, but repeated inbreeding concentrates harmful recessive genes: The royal families of Europe inbred for centuries.
Inbreeding in humans carries strong taboo associations with incest and genetic defects.
