Backcross Breeding 1 - Basic Gene Inheritance

This lesson reviews the basics of gene inheritance. It compares plants that are homozygous, heterozygous, and hemizygous for an allele and how gene expression is affected by the dominance of an allele. It also explains how to use a Punnett square to predict genotypic and phenotypic ratios of offspring.
