Cystic fibrosis is inherited as an autosomal recessive disorder. Two parents without cystic fibrosis have 2 children with cystic fibrosis and 3 children without. The parents come to you for genetic counseling. If the parents have 2 more children, what is the probability that both children will hve the same phenotype (i.e. both have cystic fibrosis or both don't have cystic fibrosis)?
