WebNational Center for Biotechnology Information WebJul 26, 2024 · When mice mate with other mice that are closely related to them (like brothers and sisters), the genetic makeup of the offspring is very similar. If this happens generation after generation, the population of mice becomes inbred, which means they’re kind of like clones of one another. In this case, inbreeding can result in smaller litters.
