Cystic fibrosis (CF) is an autosomal recessive trait. A three-generation pedigree is shown below for a family that carries the mutant allele for cystic fibrosis CF). All affected individuals are colored in, but carriers are not colored in to allow you to figure out their genotypes.    Normal allele =  F      CF mutant allele =  f        When individuals #7 and #8 had children, what was the probability that one of their children would have CF? HInt: do a Punnett square for this cross.
