Chapter 30.2, Problem 1CC
Summary Introduction
To determine:
The three ways that flowering plants avoidself-fertilization.
Introduction:
Self-fertilization is the process of fusion of the male and female gametes within the same individual. It occurs in monoecious organisms, in which both sexes are present. In flowering plants this process is equivalent to self-pollination.
