Unit B1 a - Topic 2: Genes

Scientists are able to extract and modify genes in order to change the properties of crops and animals used as food. Scientists are also able to clone organisms and some scientists hope to produce cloned body parts for transplantation surgery. Studying this topic gives students opportunities to interpret data produced through breeding experiments. Students can use various kinds of resources to consider the benefits, drawbacks and risks of scientific decisions are made and how ethical concerns of society can be considered, for example in relation to cloning.

Guidance for students: Have you ever wondered?
Are clones really like they are in the movies?

Learning objectives:

• Genetic modifications are used for a range of purposes.
• There are many ethical considerations associated with the advances in genetic modification.
