Calculate the ratios of the genotypes and phenotypes of the offspring in the F1 generation.

Answer: an FfxFf cross would produce - FF Ff Ff ff. Genotype: 1:2:1 (just look at the number of different pairs - 1 FF, 2 Ff's, and 1 ff.) Phenotype: 3:1 (because all the pairs with a capital F will appear, the only one that will not be expressed is ff, and there are FF, Ff, Ff which all have capital "F". so its 3:1.)
