WebDec 20, 2024 · Author summary Inbreeding depression is the reduction in fitness and vigor resulting from mating of close relatives observed in many plant and animal species. Mating of close relatives increases the probability that an individual inherits two non-functioning mutations at the same gene, resulting in lower fitness of such matings.

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 ].

WebJan 30, 2024 · Inbreeding depression is caused by an increase in homozygosity at a number of fitness-related loci through either overdominance or partial dominance (Charlesworth and Charlesworth 1987). Thus, inbreeding is expected to impact the expression of polygenic fitness traits that represent relatively broad targets for mutations to act upon (i.e ...
WebJun 2, 2024 · The key difference between inbreeding and outbreeding is that inbreeding is a process of mating or breeding genetically close relatives for 4 to 6 generations while outbreeding is a process of mating distantly related or unrelated individuals over 4 to 6 generations.
