Question

In humans, both cystic fibrosis and the inability to taste phenylthiourea are inherited as autosomal recessive traits. Two parents without cystic fibrosis and without the ability to taste phenylthiourea have a daughter who can taste phenylthiourea and has the cystic fibrosis condition. What is the probability that their next two children will both be born without cystic fibrosis and both have the ability to taste phenylthiourea?
