1. Hagrid has been breeding his creatures again. This time he is breeding Cerberus, his 3 headed dog. Having three heads is dominant over having 2 heads. He has also discovered that having chocolate brown fur is dominant to yellow fur. Hagrid crosses Cerberus (who is heterozygous for both traits) to a female that is also heterozygous for both traits. Hagrid's customers I want the super rare 2-headed, yellow furred dogs. What is the expected frequency of these dogs in the cross he conducts?
