A recessive disease is one such as cystic fibrosis. So, in order to have CF, a person needs a mutation in both copies of the CFTR gene.

Is cystic fibrosis caused by a dominant or recessive allele?

  • A recessive disease is one such as cystic fibrosis. So, in order to have CF, a person needs a mutation in both copies of the CFTR gene.
  • Both copies of the gene in each cell have mutations because this disorder is inherited in an autosomal recessive way. One copy of the defective gene is carried by each parent of a person with an autosomal recessive disorder, although usually neither parent exhibits the disease's signs and symptoms.
  • Parents of children with CF often experience intense emotions. Common feelings include guilt about passing on CF to your child, worry and fear for the future, and resentment for the time and care that a child with CF requires.
