Summary Introduction
To determine:
The presence of variation in offsprings if self-fertilization takes place in hermaphrodite.
Introduction:
A hermaphrodite is an animal, or plant or animal having both male and female sex organ and self-fertilization takes place by the fusion of male and female gametes from same individual.
