The gene sequence does not matter. The protein is what determines mucus production
None of the above

- 12. Multiple Choice
Could a population living today differ from their ancestors from many generations ago?
Yes, because an environment change can cause individuals to try to change some of their inherited traits.
Yes, because an environmental change can affect which inherited traits are best adapted to the new environment and which individuals are more likely to survive and reproduce
Yes, because an environmental change can cause individuals to use some of their inherited traits more than before and pass down better versions of those traits
No, they cannot differ because they have the same set of inherited traits.
