Below are a list of crosses and a list of progeny phenotypic ratios. Match each cross with the expected progeny phenotypic ratio. Write the letter corresponding to the progeny phenotypic ratio in the space provided on the right of each cross. Each progeny ratio may be used multiple times. If a cross has no corresponding progeny ratio, write an "X" in the space provided.
