WebJun 29, 2024 · Inbreeding commonly leads to inbreeding depression, the reduced fitness of individuals due to deleterious recessive (or partially recessive) mutations exposed in the homozygous state [ 8, 9 ]. In livestock, for every 1% increase in (pedigree-estimated) inbreeding, there is an estimated 0.13% decrease in the mean selected trait value [ 10 ]. Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals).
