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 codominance codominance polygenic trait polygenic trait pleiotropy

The scenario you described suggests that a mutation in a single gene affects multiple systems (immune system, lungs, heart, and kidneys), indicating that this gene has multiple effects on different traits. This is characteristic of pleiotropy. Thus, the inheritance pattern shown in this disease is pleiotropy.
