Q:
Is cystic fibrosis a sex-linked disorder?

A:
Cystic fibrosis can cause breathing problems, lung disease, nutrition problems, and problem in digestive system. If one gets cystic fibrosis, the mucus in his body will become think and block the tubes in his body.

Cystic fibrosis is not a sex-linked disorder but an autosomal recessive disorder. It means that males and females have equal possibility to inherit the gene associated with cystic fibrosis from their parents.

Only when children have inherited two copies of the mutated gene, one from the father and another from the mother, they will get cystic fibrosis. If they only inherit one copy, they will become a carrier.
