Unformatted text preview: you would get all roan calves, how would you go about this? Explain. Roat coat color is an example of codominance. By breeding a red cow (RR) and a white cow (rr), all the progeny should be roan (Rr). 4. Pure-breeding plants with red flowers were crossed with pure-breeding plants with white flowers. The resulting F1 progeny had pink flowers. These pink flower plants were crossed. What would be the expected genotypes and phenotypes of the F2 progeny? Genotypes: ¼ AA; ½ Aa; ¼ aa Phenotypes: ¼ red, ½ pink, ¼ white 5. Joe has a cat named Levin. When Joe crosses Levin with a black cat, he obtains ½ white kittens and ½ black kittens. When the black kittens are interbred, all the kittens that they produce are black. On the basis of these results, would you conclude that white or black coat color in cats is a recessive trait?
