Exam 30: Reproduction and Domestication of Flowering Plants

A parent with an S1S2 genotype exhibiting sporophytic self-incompatibility can potentially fertilize which of the following plant genotypes of the same species with pollen grains?

Recent research has shown that fertilization requires that carpels recognize pollen grains as "self" or "non-self." For self-incompatibility, the system requires

The pollen produced by wind-pollinated plants is often smaller than the pollen produced by animal-pollinated plants. A reason for this might be that
