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? Use the Punnett square below to support your answer. a) Letter that you chose to represent number of heads: b) Letter that you chose to represent the color of fur:​

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
