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)

GPT-4o mini · Answer

The correct response is **pleiotropy**. Pleiotropy occurs when a single gene influences multiple phenotypic traits. In your example, the mutation affects various organs and systems (immune system, lungs, heart, and kidneys), which is characteristic of pleiotropic inheritance. The other options (incomplete dominance, polygenic trait, and codominance) do not describe this specific scenario.
