Name the isolating mechanisms that exist within nature and indicate which ones are prezygotic and which ones are postzygotic.
Isolating Mechanisms
Biological features or behaviors that prevent species from interbreeding, thus maintaining species boundaries and genetic integrity.
Prezygotic
Referring to mechanisms that prevent fertilization or mating between species, such as geographical separation or timing differences in mating.
Postzygotic
Referring to events that occur after the formation of a zygote, affecting hybrid viability or fertility.
- Distinguish and elucidate the diverse isolating mechanisms that aid in the differentiation of species.

Prezygotic: habitat isolation, temporal isolation, behavioral isolation, mechanical isolation, and gamete isolation
Postzygotic: zygote mortality, hybrid sterility, and F2 fitness
Postzygotic: zygote mortality, hybrid sterility, and F2 fitness
