Quizplus · Accepted Answer

Reproductive isolating mechanisms are the most general category, encompassing all barriers that prevent species from interbreeding. Prezygotic isolating mechanisms are a subset of these, occurring before fertilization. Gametic isolation is a specific type of prezygotic barrier where gametes (sperm and egg) are incompatible. Pollen-stigma incompatibility is an even more specific example, applicable only to plants, where pollen cannot fertilize the ovule due to incompatibility.
