A P-generation cross was made between a true-breeding plant with yellow/round seeds and a true-breeding plant with green/wrinkled seeds. All of the F1 seeds were yellow/round. If the F1 offspring were self-fertilized, what is the expected F2 phenotypic ratio?

You breed a black, long-haired rabbit with a white, short-haired rabbit. All of the offspring have long, black hair. If the genes for hair color and length are closely linked on the same chromosome, what would you expect to see in the F2 generation?  Assume that crossing over can occur between these two genes.
