Here are some great presentations from an IB Biology teacher in Indonesia. I’m sure he’d appreciate a word of thanks if you find them useful.
Here is the document we worked through in class today, with some extra bits on meiosis too. Thanks to Mr. Boulton for the resource. Topic 10 notes
Here are some good sites for information about dihybrid crosses. There are also lots of practice problems to try. We will use these in class on Tuesday.
1. This site has a lot of clear information and activities. A good starting point.
2. This site has several problems for you to work through with nice hints to help if you get stuck.
3. The Biology Project from the University of Arizona is always worth a look, although it is quite advanced.
