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 polygenic trait polygenic trait incomplete dominance incomplete dominance pleiotropy pleiotropy codominance codominance

Answer 1

The inheritance pattern described in the scenario suggests **pleiotropy**. Pleiotropy occurs when a single gene influences multiple phenotypic traits or systems, which is consistent with the disease affecting the immune system, lungs, heart, and kidneys. Therefore, the correct answer is **pleiotropy**.
