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)

The correct answer to the inheritance pattern shown in this disease is pleiotropy.

Pleiotropy occurs when one gene influences multiple phenotypic traits. In this case, the single gene mutation affects the immune system, lungs, heart, and kidneys, which aligns with the definition of pleiotropy.
