Question

in wolves, grey coat color is dominant and black coat is recessive. brown eyes are dominant and blue eyes are recessive. if two wolves breed who are both heterozygous for coat color and heterozygous for eye color, what is the probability of them having puppies with black coats and blue eyes?
answer choices are:
3/16
1/16
9/16
6/16​

Answer 1

Answer:

1/16

Explanation:

To answer this question, you will need to set up a dihybrid cross since you have two traits that you are observing. Since the grey coat is dominant, we will label that with the genotype G and the recessive black coat will be g. Since the brown eye color is dominant, we will label that with the genotype B and the recessive blue eye color will be b. Both parent wolves will be heterozygous, which means their genotype is GgBb. Drawing the dihybrid square and filling in the spaces will allow you to have 1/16 are black coat and blue eyed puppies (ggbb). See the attached image for the cross.
