In dogs, an allergenic fur coat is dominant to a hypoallergenic fur coat. Dogs with an allergenic fur coat cause allergies, but dogs with the hypoallergenic fur coat do not cause allergies.

The black coat color is also dominant to white fur color.

Peter has horrible allergies, but he really wants a dog.

He goes to a dog breeder and says he wants a hypoallergenic Labradoodle with black fur.

Use the table of traits below to help you determine the phenotypes of the different dogs.
