Skin color is an example of incomplete dominance. In incomplete dominance, the two traits blend – just like mixing paints. Instead of the color blue being dominant to the color red or vice versa, the two colors are combined, which results in the color purple. You have just discovered that tail length in crazy creatures is also an example of incomplete dominance. One allele is for a long tail, while the other allele is for no tail. Predict what these two alleles blended would look like. Explain your prediction. 2. On Earth, flower color in snapdragons is an example of incomplete dominance. If a true-­‐breeding, red flowered snapdragon is crossed with a true-­‐breeding, white-­‐flowered snapdragon, what color flowers do you predict that the offspring will have? (show your work/punnet square) What color flowers would the second generation have if two members of the first generation were crossed? (again, show your work/punnet square) 3. Eye color in crazy creatures is an example of codominance. In codominance, an organism that has both alleles of a gene displays both traits at the same time. How is this different than incomplete dominance? 4. On Earth, a cross between a black cat and a tan cat results in a tabby cat (black and tan mixed together). What do you think the offspring of a tabby cat and a black cat would look like? (show your work) 5. If a black chicken is crossed with a white chicken in a certain species, the offspring are spotted black and white. These chicken are an example of which pattern of inheritance? 6. In another species of chickens, a cross between a black chicken and a white chicken produces blue chickens. These chickens are an example of which pattern of inheritance?
