5. Watch and summarise what this video is about
Video is about there being a gene for bad behaviour and if it is a good predictor for a violent individual

6. Bad behaviour genes Was bad behaviour completely genetic?
What other factors made people more likely to have good or bad behaviour?

7. Variation
Variation is all the differences which exist between members of the same species.
What things make humans different from one another?
Make a list/thought cloud!
List all the ways in which we can be different from one another.. Hair (colour, length, style), scars, accent, height etc

8. Environmental variation
There are 2 types
Environmental variation
Genetic variation

9. completely environmental
You each have 12 cards showing different characteristics. In pairs, decide how much of the variation in each characteristic is due to genes (inherited variation) and how much is due the environment Put the cards on a line like this: You have 8 minutes to sort all the cards Be ready to share your reasons why you put them where you did!
completely genetic
completely environmental

10. How do we know what causes variation?
Same genes
Different environment
Same environment
