Cystic fibrosis is an autosomal recessive genetic disease.
CF is a serious and chronic disease of the lungs, it has nothing to do with sex, except that it can affect both males and females.
The genes on each chromosome control specific functions of the human body. The gene on chromosome 7 produces a protein called cystic fibrosis transmembrane regulator. Mutation in the DNA level of chromosome 7 leads to the absence of this protein which leads to cystic fibrosis. Cystic fibrosis is a recessive disease. It means that both copies of the gene must be defective. An affected person will have abnormal cystic fibrosis transmembrane regulator gene on each chromosome 7. Therefore both biological parents must have an abnormal gene. One abnormal copy is inherited from each parent. A person with one normal gene and one abnormal gene is called a cystic fibrosis carrier. Cystic fibrosis carriers do not show any symptoms but they may pass the abnormal gene to their children. Therefore the parents can be either cystic fibrosis carriers or affected themselves.
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
Sex-linked traits have alleles that are passed from parent to child on a sex chromosome.
Sex-linked is an adjective describing the noun gene.
Sickle cell anemia and cystic fibrosis are carried on autosomes (chromosomes other than the sex chromosomes). Probably too many to list . . Right now, off the top of my head, I can think of Down's Syndrome (21st chromosome) and the "cri du chat" (5th chromosome) . . .
The gene for hemophilia is sex-linked.
No, a gene is either autosomal or sex-linked, but never both.
