Answer 1

Based on the information provided in the Punnett square, if a dog's genotype is aabb, we can look at the potential phenotypes for that genotype.

Within the table, we see that the genotype aabb corresponds to the fur color:

• aabb = yellow

Therefore, the color of the dog's fur would be yellow.
