Cystic fibrosis is controlled by recessive alleles (cc). if two parents without cystic fibrosis have a child with cystic fibrosis, what is the probability ratio that their next child will have cystic fibrosis?

Homologous recombination occurs in a heterozygote in which alleles D and d differ by a single base pair. The D allele has a G (a GC base pair) at one position, whereas the d allele has a C (a CG base pair) at the same position.
