Are self-fertilizing plants their own worst enemy?plants
It’s called self-fertilizing or “selfing” and, while it guarantees reproduction, plants that practice it may be contributing to their own demise.
Self-fertilizing in plants can lead to reduced diversity and an increase in mutations. Above at left: a selfing derivative species of Capsella rubella, red shepherd’s purse; at right: Capsella grandiflora, outcrossing species
