Plant Breeding and Predicting Offspring Traits

Introduction
Kernel color in an easily observable trait. There are different alleles of the ‘kernel color’ gene that code for different colored kernels. For example, one allele represented with Y (upper-case) encodes yellow colored kernels. Another allele for the color trait encodes white colored kernels represented with the y (lower-case).
Plant obtain energy through photosynthesis .They are producers because they are able to obtain synthesize their food . Animals on the other hand are consumers and must obtain their energy by consuming organic matter such as plants and animals .
