An ecologist has been following three single gene traits in laboratory breeding experiments of frogs. Texture and Color of the skin and the extent of webbing between the digits. The dominant traits in each case are Warts (vs smooth), Red (vs green) and Webbed (no-webbing). Wild type frogs have smooth, green skin with webbed feet. We want to breed a frog that has all three mutant phenotypes. Cross 1 – We made a dihybrid frog by crossing an inbred color mutant with an inbred texture mutant. Cross 2 - We crossed this dihybrid with an inbred non-webbed mutant. Question: What fraction of progeny will be the desired triple mutant from cross 2. Write out the work flow to solve this problem.
