Hi student!!
Thank you for your great question! The answer to your question is yes. The scientific advances (progress that has been made) most definitely refers to the "emergence of the tomato genome sequence." Having a better understanding of the DNA of tomatoes as has allowed Klee's work to "really accelerate."
Great job arriving at the correct answer even though you weren't fully certain about the question. It shows great reasoning abilities. =)
Keep Moving Forward!
