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.

Substrate-binding could cause a conformational change to take place in the enzyme and reveal an inhibitor binding site, or the inhibitor could bind directly to the enzyme-bound substrate.
