The ABO and MN blood groups are given below for four set of parents (1 to 4). Recall that the ABO blood group has three alleles: IA, IB, and i. The MN blood group has two codominant alleles, M and N. Its three blood group phenotypes, M, MN, and N, correspond to the genotypes MM, MN, and NN. The ABO blood groups assorts independently of the MN blood group.Using your knowledge of these genetic systems, who are the parents of a child with blood type O and M blood group? Select the right answer and show your work on your scratch paper for credit.

In rats, gene B produces black coat color if the genotype is B-, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D-, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream.  The genotype of parents of litters with the following phenotype distribution 3 brown, 3 yellow, 1 black, 1 cream is: Select the right answer and show your work on your scratch paper for credit.

Dr. Barbara McClintock, a famous geneticist, decides to try her hand at iris propagation. She selects two pure-breeding irises, one red ad the other blue, and crosses them, To her surprise, all F1 plants have F1 purple flowers. She decides to create more purple irises by self-fertilizing the F1 irises. Dr. McClintock produces 480 F2 plants consisting of 362 with purple flowers, 89 with blue flowers and 29 with red flowers. Which of the following epistatic interactions might account for her observations? Select the right answer and show your work on your scratch paper for credit.  

There are two forms of human earwax: wet and dry. W is a dominant allele that produces wet earwax. In a sample of Spaniards, you measure the following genotypes: WW= 840, Ww =120, and ww = 40. What is the frequency of the heterozygous genotype? Select the right answer and show your work on your scratch paper for credit.
