In Primula vulgaris (primrose), purple flowers are dominant to white flowers, and short plants are dominant to tall plants. The genes controlling these two traits are on different chromosomes. You cross a true-breeding purple, short plant with a true-breeding white, tall plant and then intercross the resulting F1 offspring. In the F2 offspring, you find the following phenotypes: Purple, short Purple, tall White, short White, tall 608 161 173 58 With your knowledge of the x? test, you will determine whether the outcomes of the F1 intercross corresponds to expectations based on Mendelian genetics. 1. What is your null hypothesis for the outcome of the F1 intercross? Write it here: 2. Based on your null hypothesis, how many individuals do you expect in each of the phenotypic classes? Write your expectations below. Purple, short _Purple, tall _White, short White, tall 3. What are the degrees of freedom for this test? Write your answer here:
