NEET BIOLOGY

Detailed explanation-1: -In people with CF, mutations in the CFTR gene can disrupt the normal production or functioning of the CFTR protein found in the cells of the lungs and other parts of the body. Cystic fibrosis is an example of a recessive disease. That means a person must have a mutation in both copies of the CFTR gene to have CF.

Detailed explanation-2: -It is caused by a faulty recessive allele on chromosome 7. To be born with cystic fibrosis, a child has to inherit two copies of this faulty gene-one from each of their parents. Their parents will not usually have the condition themselves, because they will only carry one faulty gene and one that works normally.

Detailed explanation-3: -Mutations in the CFTR gene cause cystic fibrosis. The CFTR gene provides instructions for making a channel that transports negatively charged particles called chloride ions into and out of cells.

Detailed explanation-4: -Autosomal Recessive: Cystic Fibrosis, Sickle Cell Anemia, Tay-Sachs Disease. We inherit genes from our biological parents in specific ways. One of the ways is called autosomal recessive inheritance.
