Dihybrid Cross

Once you understand monohybrid cross, dihybrid cross is basically the same thing. However, In contrast to a monohybrid cross, a dihybrid cross is a cross between F₁ offspring (first-generation offspring) of two individuals that differ in two traits of particular interest. For Dihybrid crossing, there are always 2 different traits Represented by different alphabets, for example let R be a dog with Red eyes and r be black eyes while Y be yellow skin and y be white skin. The question might be something like what are the genotype and phenotype ratios if you mate two heterozygous dogs together, which in this case would be RrYy X RrYy. And then basically you simply isolate the Rr X Rr and Yy X Yy and do the punett squares for both of them, then you multiply the results to get the ratios. Not rocket science.
