Question

Does the cystic fibrosis allele protect against tuberculosis?

1) Yes
2) No
3) Not enough information to determine

Answer 1

No, the cystic fibrosis allele does not protect against tuberculosis. Having the cystic fibrosis allele actually makes individuals more susceptible to respiratory infections, including tuberculosis.

Step-by-step explanation:

No, the cystic fibrosis allele does not protect against tuberculosis. Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene, which leads to the production of thick, sticky mucus in the lungs. This mucus can impair the lung's defense mechanisms, making individuals with cystic fibrosis more susceptible to respiratory infections, including tuberculosis. Therefore, having the cystic fibrosis allele does not provide any protection against tuberculosis.
