Principle Of Inheritance And Variation Question 513
Question: Which of the following is not a hereditary disease [CBSE PMT 2005]
Options:
A) Cretinism
B) Cystic fibrosis is a genetic disorder that affects the lungs, pancreas, and other organs. It causes thick, sticky mucus to build up in the lungs and obstruct the pancreas, leading to chronic lung infections and digestive problems. The disease is caused by mutations in the CFTR gene, which regulates the movement of salt and water in and out of cells. Cystic fibrosis is inherited in an autosomal recessive pattern, meaning a person must inherit two defective copies of the CFTR gene, one from each parent, to have the disease. There is no cure, but treatments can help manage symptoms and improve quality of life.
