This powerpoint presentation covers Topic 4.1 (Chromosomes) in the IB Biology curriculum. Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes.
The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
