Inbred species
WebInbreeding appears universally to reduce fitness, but its magnitude and specific effects are highly variable because they depend on the genetic constitution of the species or populations and on how these genotypes interact with the environment. WebThis leads to a decline in performance called inbreeding depression. This phenomenon is well documented in all of the major livestock species. It is essentially the opposite of heterosis which is the advantage gained from crossing lines or breeds. Measurement of Inbreeding . Inbreeding in an individual is measured with the inbreeding coefficient.

For these breeds, those slopes are about 0.1, which means that an increase in inbreeding of 10% reduces litter size by about 1. If normal litter size is about 6, a COI of 30% - which is not uncommon in many breeds - would reduce the litter size by HALF.
