Summary Introduction

To determine: How self-incompatible species are in severe population bottleneck compared to self-fertile species.

Concept introduction: Self-incompatibility is a genetic mechanism in angiosperms, which prevent self-fertilization from inbreeding and promote the generation of new genotypes in plants, and thus encouraging the outcrossing process. This is the major reason for the success of angiosperms on the earth. Selection may favor partial or complete loss of these species, because they develop zero to very low seeds. The females are more likely to receive an inadequate amount of pollen in self-incompatible conditions.
