Question

Practice Problem 5 Purebred dogs are susceptible to many genetic disorders. Cocker spaniels, in particular, are prone to a disorder called canine phosphofructokinase (PFK) deficiency, an autosomal recessive condition in which glucose is unable to be metabolized into available energy. Because the PFK enzyme is important for energy metabolism in red blood cells and skeletal muscle during exercise, a deficiency in the enzyme results in exercise intolerance and muscle disease Use the pedigree below, which shows the inheritance of PFK deficiency in cocker spaniels, to answer the questions. Hailey's parents Henry's parents Hailey Henry Halle Hazel Hank OO Howey

Answer 1

Part C What is the probability that Howey and Hailey's unaffected female offspring will be carriers of PFK deficiency? They have 3 female in that one affected so other two may be carriers = 2/3 O 0% 67% O 25% O 50% 67% O 75%
