What is a mutation?
A random change to a gene that sometimes results in a new trait.

What is an adaptive trait?
a trait that makes it more likely that an individual will survive in a specific environment

What is the non-adaptive trait in regards to the newt?
Low poison level
200
Any differences in traits between individual organisms
Variation
300
True or False. Mutations to a gene ALWAYS make a new trait.
