Question
What is inbreeding depression? Why do the self-pollinated crops not show the ill effects of inbreeding depression?

The continuous inbreeding may lead to reduced fertility and productivity called inbreeding depression. Self-pollinated crop does not show the ill effects of inbreeding depression because the deleterious allele becomes homozygous and exhibits their lethal effect so it is eliminated by selection.
