Genetic Mutation

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

How to tell they’ve got it

Tick these off as you see them — no test required.

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

Try this 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?
