Binding of RISC complexes causes the bound mRNPs to associate with P bodies. Since P bodies are major sites of mRNA degradation where the decapping complex DPC1/DPC2, t5′→3′ exonuclease XRN1, and cytoplasmic exosomes are concentrated, mRNAs bound by several RISC complexes are degraded.

Positive assortative mating

Individuals' mate with others who are like themselves phenotypically for selected traits. The net effect of positive assortative mating is a progressive increase in the number of  homozygous genotypes (AA and aa)

Inbreeding

Preferential mating between related individuals. Inbreeding is more likely to take place in nature when population size becomes very small, and the number of mates is limited.
