Which of the following is TRUE about selective breeding and genetically modified organisms?
GMOs are always superior to selectively bred organisms. Vitamin A genes have been introduced into rice to make these crops resistant to pests. GMO plants are now more common in the world's food supply than wild plants. Desired traits engineered into crops must come from DNA of the same species (e.g. rice genes must always be used to genetically engineer rice). Farmers have been able to produce new varieties of crops by selective breeding alone.
