Good review presentations

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 is the syllabus guide for Topic 10 – the HL stuff on meiosis and genetics.    IB Biology HL Topic 10 – syllabus guide

It should help you prepare for your test NEXT WEEK.  Mark your diaries – Thurs 20th August.  The majority of the questions will be on Topic 10, but I reserve the right to throw in a few from Topic 4 – Syllabus outline (SL genetics) for good measure.  Format will be IB past paper questions, both multiple choice and short answer.

Dihybrid crosses

Monday, August 10th, 2009

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.
