What is the function of the FOIL method in a Dihybrid Punnett Square?

The function of the FOIL method in a Dihybrid Punnett Square is to solve for gametes. When dealing with two traits, each represented by a pair of alleles, the FOIL method helps in systematically determining all possible combinations of these alleles in the gametes produced by each parent. FOIL stands for First, Outside, Inside, Last, referring to the order in which you multiply the allele combinations of each parent. This results in a complete set of gametes that can be used to fill out the Punnett Square, ultimately allowing for the prediction of offspring genotypes. Understanding this method is essential for analyzing inheritance patterns of multiple traits simultaneously.
