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.
