2. A researcher studying hoof color in reindeer found a number of mutants with white hooves. Thinking that these might be advantageous in avoiding predators in a white snowy environment the researcher went on to do a complementation analysis. The researcher was able to show that all mutant lines were true breeding and then did all of the pairwise crosses as shown below (15). Color Genotype Wildtype Black Mutant 1 White Mutant 2 White Mutant 3 White Mutant 4 White Mutant 5 White Mutant 6 White A. How many different genes were altered in the above mutants using just the information from the table (3)? B. Write in the genotypes for mutants number 1 through 5 above (6) C. Describe the relationship of all alleles at any gene you have identified (2) D. How would you have to amend your answer if you were told upon selfing the F1 individual from the M1 x M3 cross, that the F2 had a ratio of 27 Black to 37 White (4)? 4
