Question

Explain pre -mating or pre - zygotic isolating mechanism giving any three types.​

Answer 1

Prezygotic barriers include habitat isolation, behavioral isolation, temporal isolation, mechanical isolation, and gametic isolation. In habitat isolation, two organisms that use different habitats (even in the same geographic area) are unlikely to encounter each other to even attempt mating.

Pre-zygotic isolation. Pre-zygotic isolation mechanisms are the most economic in terms of the natural selection of a population, as resources are not wasted on the production of a descendant that is weak, non-viable or sterile. These mechanisms include physiological or systemic barriers to fertilization.
