Cystic fibrosis is a genetic factor because it is a hereditary condition caused by a mutation in a specific gene. This gene is responsible for producing a protein that regulates the movement of salt and water in and out of cells. When this gene is mutated, it leads to the production of a faulty protein, causing the buildup of thick, sticky mucus in various organs, particularly the lungs and digestive system. This genetic factor is inherited from both parents and can be passed on to future generations.
