Genetic Alchemy: Turning Lobsters into Fruit Flies

1. What is a hox gene?

2. What happens if the Ubx gene is removed from insects?

3. How does the Ubx gene provide evidence of evolution?

4. How does a mutation on one chromosome (of a hox gene) cause an entire change in morphology - why aren't mutations needed on both chromosomes?

5. Hox genes are found on all organisms. Why is this significant?
