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 codominance codominance pleiotropy pleiotropy incomplete dominance

The scenario described indicates that a single gene mutation is responsible for a genetic disease affecting multiple systems in the body (immune system, lungs, heart, and kidneys). This phenomenon is best explained by the concept of pleiotropy, where one gene influences multiple phenotypic traits or systems.

Therefore, the correct response is: pleiotropy.
