Summary Introduction
To determine:
The frequency of progeny having the dominant
Introduction:
Self-fertilization is the phenomenon of fusion of male and female gametes which are produced by the same individual. The phenomenon occurs in bisexual organisms such as flowering plants and many invertebrates.

She knows that one plant may contain hundreds of individual seeds, each resulting from a separate fertilization event. She determines that a single gene controls seed color with two alleles-the dominant allele results in black seeds, and the recessive allele results in brown seeds.
