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. http://www.informatics.jax.org/greenbook/chapters/chapter2.shtml

WebHere we examine ancestry, population structure, and inbreeding using SNP microarray genotypes in a cohort of 814 wild mice spanning five continents and all major subspecies of Mus, with a focus on M. m. domesticus. We find that the major axis of genetic variation in M. m. domesticus is a south-to-north gradient within Europe and the Mediterranean.

Inbreeding is defined as the probability of two alleles in an individual being identical by descent, and is normally the result of mating related individuals.
