How Was "Genetic Engineering" Used in the Development of Modern

question 22

Multiple Choice

How was "genetic engineering" used in the development of modern corn from its relative teosinte?

• A) People harvesting the teosinte selected the plants with more desirable traits and so those genes spread in the population, eventually resulting in modern corn.
• B) People got tired of harvesting the teosinte as it was, so they cross pollinated it with other plants with seeds on cobs, and wound up with modern corn
• C) People selected the genes which controlled cob and kernel size in teosinte and inserted them into related plants, eventually developing modern corn
• D) People harvesting corn plants selected desirable traits and ended up with modern, large cob teosinte, now known as modern corn
• E) Scientists have found five genes which control the differences between teosinte and modern corn, but cannot determine how they were engineered from one to the other
