Is there a quick way of calculating the genotypes and phenotypes of a Dihybrid cross? For example: Ggss x ggSs.

I've found that just breaking them up into individual alleles to see the ratios then matching them with the answer choices is easiest. The answer choices will most likely be in large numbers which you can simplify into bare ratios (kinda like empirical formula in gen chem), then just match them up.

Maybe someone else has a faster trick...? This usually doesn't take more than a minute or two though.
