Papaya plants have male and female flowers on separate plants. Thus papaya is considered to be dioecious.
Maize plants bear both the male and the female flowers on the same plant. Hence these are said to be monoecious.
Self-incompatibility is an outbreeding device that prevents self-pollen from fertilizing the ovule by preventing pollen germination in the pistil or pollen tube growth.
Continued self-pollination result in inbreeding depression.
