You have genetically engineered a tomato plant to be resistant to an insect pest by introducing a gene into tomato seeds that codes for a protein that is poison to the insect, but harmless to humans. After several generations you have obtained a true-breeding line of insect resistant tomatoes. Is the insect-resistance trait likely to be dominant or recessive? I would think recessive only because it needs to go several generations before it becomes true-breeding. Can someone please give me a good explanation?
