Question

Is cystic fibrosis an example of Pleiotropy?

Answer 1

Pleiotropy:

1. In genetics, pleiotropy is the expression of multiple traits by a single gene.
2. Pleiotropy comes from the Greek word for “many ways.”
3. Cystic fibrosis, a genetic disorder, is one of the most common examples of pleiotropy.
4. It's a gene with multiple functions. Cystic fibrosis affects the cells responsible for the production of mucus, sweat, and digestive juices.
5. Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits.
