The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups.
<h3>How do phenotypic classifications work?</h3>
The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups. If any of the single homozygous recessive genotypes (i.e., A bb or aaB_) exhibits the same phenotype as the double homozygous recessive (aabb), then a 9:3:4 phenotypic ratio will result. 
<h3>What does phenotypic classification entail?</h3>
phenotype, all of an organism's observable traits that emerge from the interaction of its genotype (total genetic inheritance) and environment. Observable features include things like behavior, biological characteristics, colour, shape, and size.
