Question

Now you conduct breeding experiments with the elusive Torero turtle. You see that they come in two colors, but the colors are controlled by two genes that are on separate chromosomes. One gene determines whether any color will be present at all - with color dominant to no color. The second gene determines which color pigment would be produced, brown or yellow, with brown being dominant . Here, let B= brown, b=yellow, C=color, c=no color.

a) If you cross CCBB X ccbb, what do you expect that phenotype and genotype of the F1 to be?

b) If you were to cross F1 with each other, what phenotypic ratio would you expect in the F2? Which genotypes would underlie each F2 phenotype?

Ratio Phenotype Genotype(s)

c) What is this genetic mechanism called (when one gene modifies the effects of another gene)?

Explanation / Answer

a. brown phenotype, CcBb genotype for all b.
