The biotechnological methods used by two geneticists on a high-yielding rice variety are described below. Method X: Increased the rice yield by combining genetically similar rice varieties over several years Method Y: Inserted the vitamin A production gene from carrot in the rice Which method is likely to be more advantageous? Method Y because it increases the gene pool Method X because it protects the variety from diseases Method X because it increases long-term survival of the variety Method Y because humans who eat the rice can also develop the same gene
