Quick Recall Flashcards

What is cystic fibrosis and how is it inherited?

Cystic fibrosis is a recessive disorder caused by having two copies of the faulty allele (ff). It causes thick, sticky mucus to build up in the lungs and digestive system, leading to breathing difficulties and frequent infections.

What is polydactyly and how is it inherited?

Polydactyly is a dominant disorder — having just ONE copy of the dominant allele (Pp or PP) causes extra fingers or toes. Only one affected parent is needed to pass it on. It is usually not harmful and can be corrected surgically.
