Success Criteria

• To understand what Selective Breeding is

• To understand the process of genetic engineering

Task: Create a poster/information sheet on:

- Selective Breeding

- Genetic Engineering

You must define what the process is and explain how it is carried out.

Please use the KAYScience videos and BBCbitesize links from the chat to help you.
