Answer Details
The practice of mating closely related animals is called in-breeding.
In-breeding is when animals who are closely related to each other, such as siblings or parent-offspring, are bred together. This can increase the likelihood of genetic disorders and other health problems in offspring, as well as reduce overall genetic diversity. It is generally not recommended in animal breeding programs and is only done in certain circumstances, such as when attempting to preserve a rare breed.
