Shading in each punnett square represents matching phenotypes, assuming complete dominance and independant assortment of genes, phenotypic ratios are also presented. In this example, both parents are heterozygous for flower color ( bb ). This is considered to be advanced mendelian inheritance forming the logical extension from prior learning about the dihybrid cross. Only shown if a gene is homozygous recessive.
A commonly discussed punnett square is the dihybrid cross.
