Dihybrid crosses don't require memorizing all 16 offspring combinations by hand. The same FOIL (First, Outer, Inner, Last) method used to expand binomials in algebra can generate the parent gamete combinations that become the row and column headers of a Punnett square. Studying genetics becomes faster when you reuse tools you already know from math rather than treating each subject as isolated.
