Is CF X-linked or incomplete dominance?

Answer 1

Neither. The gene for cystic fibrosis is an autosomal recessive gene. A person must inherit two recessive genes in order to be affected.

Answer 2

Cystic fibrosis (CF) is an autosomal recessive disorder, not an X-linked disorder. It means that both copies of the gene responsible for CF need to be mutated in order to develop the disorder. Incomplete dominance refers to a genetic trait where the heterozygous condition results in an intermediate phenotype, which is not the case for CF.
