Question 3

Describe the benefits of self-incompatibility and self-compatibility.

Accepted Answer

A benefit of self-incompatibility is that it prevents inbreeding. Inbreeding can result in deleterious mutations. Self-incompatibility promotes genetic variation by increasing the probability of outcrossing. Self-compatibility can benefit a plant population by preserving adaptive traits. In addition, a self-compatible plant does not have to rely on wind or animals for pollination, and therefore can ensure that seeds can form.
