(HELP ASAP) Cystic fibrosis is one of the most common genetic diseases in America. It is estimated
that 1 in 23 Americans are carriers for Cystic Fibrosis. Cystic Fibrosis is a recessive trait
that follows Mendel's Law of Dominance.
Answer ALL parts of the free response below - be sure to use vocabulary and explain your
response in detail:
A. Explain what Mendel's Law of Dominance means

B. Explain how 2 parents who do NOT have Cystic Fibrosis could have a child with cystic
fibrosis.

1.

Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.

2.

A person with one non-functional copy of the gene is a carrier. Carriers for CF have no symptoms, but can pass the non-functioning gene on to their children. An individual must inherit two non-functioning CF genes – one from each parent – to have CF. More Information Below

~A person must inherit 2 CF genes to have CF disease. When your child was conceived, he or she received a CF gene from both you and your partner. A child can inherit CF only if both parents carry a CF gene (that is, each parent either has CF or is a carrier) and both parents pass the CF gene on to their child.~
