Punnett Square Example - Dihybrid Cross

The video tutorial explains how to construct and analyze a Punnett square for a dihybrid cross, using Guinea pigs as an example. It covers the setup of the cross, determining allele combinations using the FOIL method, and filling the Punnett square. The tutorial also discusses the genotypic and phenotypic ratios of the F1 and F2 generations, highlighting Mendel's law of independent assortment.
