Question

A genetic disease is found in a family that affects the immune system, lungs, heart, and kidneys. A DNA analysis of several affected and unaffected family members determines that the disease is caused by a mutation in a single gene. What type of inheritance pattern is shown in this disease?(1 point) Responses incomplete dominance incomplete dominance pleiotropy pleiotropy polygenic trait polygenic trait codominance

Answer 1

The correct response for the inheritance pattern shown in this disease is **pleiotropy**.

Pleiotropy occurs when a single gene affects multiple traits or phenotypic features. In this case, the mutation in a single gene is causing effects on the immune system, lungs, heart, and kidneys, indicating that one gene is influencing several different biological systems or features.
