A dioecious flowering plant prevents both:

Solution & Step-by-step Explanation

In a dioecious plant, male and female flowers are on different individual plants. This prevents: Autogamy: Pollen from the same flower. Geitonogamy: Pollen from a different flower on the same plant. It forces Xenogamy (cross-pollination).

Try it yourself before checking the explanation above.
