What does inbreed mean?
Inbreed means to reproduce among individuals that are closely related or belong to the same restricted genetic line. The process can concentrate inherited traits, including harmful recessive variants, and reduce genetic diversity. In biology and animal breeding, it may occur naturally when populations are isolated or when breeders repeatedly pair close relatives. The related noun inbreeding names the practice, while inbred describes organisms, populations, or traits resulting from it. Although the word is sometimes applied more broadly to reproduction within a closed social group, its central meaning is specifically genetic. Understanding inbreeding is important in conservation biology, agriculture, medicine, and the care of captive animal populations, where genetic diversity and the appearance of inherited disorders must be managed.

Inbreeding is a natural process, but it can make rare genetic disorders more likely to appear by concentrating harmful traits within a population.

Where does inbreed come from?
The word combines the English prefix in-, meaning “into” or “within,” with breed, the older verb associated with producing offspring or developing a characteristic. The core sense developed from the idea of breeding within a limited family or genetic line. The related noun inbreeding and adjective inbred were formed from the same compound, while breed and brood reflect older Germanic vocabulary connected with rearing and producing offspring.
