Correct Answer is C

Explanation

A) Incorrect. CF is not caused by an extra chromosome; it is a genetic disorder resulting from mutations in specific genes.

B) Incorrect. CF is not characterized by a duplication of the CFTR gene but rather by various mutations in this gene.

C) Correct. CF is primarily caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene, leading to the production of dysfunctional chloride channels.

D) Incorrect. CF is not characterized by the absence of the CFTR gene; instead, it involves various mutations in this gene.

A. "CF is caused by a single gene mutation, which can be inherited from one parent." B. "CF results from a combination of genetic and environmental factors." C. "CF occurs due to an X-linked genetic mutation passed from mother to daughter." D. "CF is primarily caused by exposure to respiratory pathogens during infancy."

Correct Answer is A

Explanation

A) Correct. CF is primarily caused by mutations in a single gene, the CFTR gene, and it can be inherited from one parent, resulting in a carrier state, or from both parents for the disease to manifest.

B) Incorrect. While genetic factors are the primary cause of CF, environmental factors can exacerbate symptoms but are not the root cause.

C) Incorrect. CF is not an X-linked genetic disorder; it follows an autosomal recessive pattern of inheritance.

D) Incorrect. CF is not caused by exposure to respiratory pathogens during infancy; it is primarily a genetic disorder.
