How can you tell they’ve got it: Genetic Mutation?

If they’ve got it, you’ll see things like: Defines mutation as a change to DNA sequence; Names at least two things that can cause mutations (mutagens); Explains that mutations are the original source of all genetic variation; Explains that beneficial mutations can be selected for by natural selection. Or just try it together: If your child heard that DNA can get damaged or changed, could they explain what a mutation is, what might cause one, and why most mutations don’t actually cause problems — but occasionally one leads to something new?

Genetic Mutation

Your child knows a mutation is a change in DNA. Radiation, chemicals, or copying errors can cause one. Most do no harm, but now and then one brings something new.

In curriculum terms

Explain genetic mutation as a random change in DNA sequence, describe causes of mutation (e.g. radiation, chemicals, copying errors), and explain that most mutations are neutral, some harmful, and a few beneficial
