Directions: Answer questions A-D below. Use letters A-D to indicate which part of the question you are answering. Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If the capital letters represent dominant, independently assorting alleles: A. How many different genotypes will occur in the F2? _________ B. What proportion of the F2 genotypes will be recessive for all five loci? ______   C. Would you change your answers to part (a) and or part (b) if the initial cross occurred between AAbbCCddee x aaBBccDDEE parents?   D. Would you change your answers to part (a) and/or part (b) if the initial cross occurred between AABBCCDDEE x aabbccddEE parents?
