You mate a normal mouse (short hair, big eyes, 5 toes, solid coat color) with one that has long hair, micropthalmia (small eyes), polydactyly (extra toes), and spottedcoat color. The F1 offspring are normal (short hair, big eyes, 5 toes, and solid coatcolor). You intercross the F1 offspring. What fraction of the F2 would you expect to have micropthalmia and polydactyly but be otherwise normal?
