... When are Punnett Squares not useful? When only two pairs of genes are involved, you can solve the problems with Punnett squares. With three or four or more pairs of genes, the phenotype distribution begins to resemble a bell-shaped curve; then it's easier to estimate or "eye-ball" predictions. ...
