Animal research in genetics

IB Psychology: Animal research in genetics

One of the ways that animals are used in genetic research is through selective breeding experiments. This is when animals are bred with the goal of producing a specific phenotype. Modern research using selective breeding often uses transgenic mice – that is, a mouse that has had a single gene changed or removed. In 2007 Mario Capecchi, Oliver Smithies and Martin Evans won the Nobel Prize in Physiology for developing...

Just about to teach HL for biological approach. One of the possible exam questions on in thinking is discuss the use of animal models in genetic research does that mean for each topic of biological approach I need to teach 2 animals studies? Or does it mean that the student would discuss one human study first and then to what extent an animal study corroborates that finding?

Dear Megan

I think that to play it safe, yes, they will need two animal studies for each question. I think that this is a bit much, IMHO. I think that if the question is about generalization that a human study is appropriate, but if it is only about the use of animals in genetic research, then two studies will be necessary.
