Assume that a particular genetic condition in a mammalian species causes an inability to digest starch. This disorder occurs with equal frequency in males and females. In most cases, neither parent of affected offspring has the disorder.
a. Describe the most probably pattern of inheritance for this disorder. Explain your reasoning.
b. In the Punnett square provided, enter a sample cross that verifies the pattern you proposed in part a above.
c. Explain how mutation could cause this inability to digest starch (hint: genes, enzymes).
