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

Or

Fungus Trichoderma polysporum proved to be very essential to organ transplant patients. Give reason.

Answer:

Inbreeding depression is reduced fertility and productivity due to continuous inbreeding. Self - pollinated crops do not show the ill - effects of inbreeding depression because the deleterious alleles become homozygous and exhibit their lethal effects. Therefore, they are eliminated by selection.

Or

Trichoderma polysporum is a fungus which is proved to be very essential to organ transplant patients because it produces a bioactive molecule called cyclosporine - A. This cyclosporin - A is used as an immunosuppressive agent in organ transplant patients.
