"WebInbreeding is when the animals bred are very close relatives, such as siblings. Continued inbreeding results in offspring that are very genetically alike. After many generations of inbreeding, the offspring will be almost genetically identical, and will produce identical offspring. When this happens, an organism is described as inbred or purebred.
