Since inbreeding brings out the hidden recessive genes, the homozygous animals as well as many of the heterozygotes could be identified and culled. But again, this would require severe cull ...

... Also at single-locus traits the result of inbreeding is an increased frequency of homozygotes, and thereby inreased frequency of harmful, recessive alleles in double dose so that they manifest in disease/death. This has been thoroughly documented in studies on offspring from related parents. For mul ...
