Mechanisms of Reproductive Isolating | Evolution | Biology

A reproductive isolating mechanism is a structural, functional, or behavioural characteristic that prevents successful reproduction from occurring between different species. This helps in accumulating genetic variations in species. If reproductive isolation does not exist, variant forms freely interbreed with the normal forms and this would lead to intermixing of their genotypes. These mechanisms are of two types: 1. Pre-Mating Mechanisms: [...]
