Problem
Chance and Probability only apply to situations that are unknown Sometimes we know a person's genotype, or we know what genotype a person is not. Remember that while you work the following problem. a. Cystic fibrosis is a disease that affects people who have two recessive alleles (ff). Two parents with the heterozygous genotype for cystic fibrosis (Ff) have a daughter with a normal phenotype. The daughter wants to have a child but wonders what the chance is that she is a carrier heterozygousnd therefore capable of passing the recessive allele to her child. What can you tell her?
