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.Research conducted by the National Institute of Genomic Medicine reveals that rural areas in countries like India, Pakistan, and even parts of the Americas face this challenge.
