WebNov 30, 2024 · Inbred individuals express deleterious, partially recessive alleles that are inherited identically by descent (IBD) from related parents, leading to inbreeding depression ( 16 ). Such inbreeding depression can reduce the average fitness of a population, eventually leading to reduced population size and possibly extinction ( 17 ). 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 ...

Inbreeding is basically breeding between individuals who are genetically closely linked, such as first and second cousins.
