For the effective detection of genetically modified components of plants, the necessary condition is that the breeder provides sufficient and complete information to the test subject. If the test subject and the breeder are within the jurisdiction of the national government, the breeder provides sufficient and complete information to the test subject It is a controllable operation process within the country's sovereignty; but if the breeder and the tester belong to different countries, especially when the technical ability of the breeder is ahead of the tester, it is difficult for the tester to ask the breeder to provide the seed Full and complete information. From this, it can be inferred? ['Effective detection of genetically modified ingredients in plants is an impossible task.', 'If the breeder can provide sufficient and complete information, the plant can be effectively tested for genetically modified ingredients.', 'The breeder and tester of a certain plant belong to different countries, and it is easier to test the genetic composition of the plant.', 'If the plant can be effectively tested for genetically modified ingredients, the breeder has provided the test subject with sufficient and complete information.']
