Is cystic fibrosis non disjunction

Cystic fibrosis is not caused by nondisjunction; it is a genetic disorder resulting from mutations in the CFTR gene, which is typically inherited in an autosomal recessive manner. Nondisjunction refers to the failure of chromosomes to separate properly during cell division, leading to an abnormal number of chromosomes in gametes. While nondisjunction can lead to conditions like Down syndrome or Turner syndrome, cystic fibrosis is specifically linked to changes in a single gene rather than chromosomal abnormalities.
