The soybean aphid was introduced to the United States in 2000. The aphid killed many soybean plants. In 2004, scientists

discovered that some soybean plants were resistant to the aphid. This resistance was genetically based. The scientists
wanted to determine whether the resistant trait in these soybean plants has a dominant inheritance pattern. Which of the
following would provide the best evidence that the trait is dominant?
