But my students and I struggled a bit with making the modifications in order to answer interesting questions. However, with all struggle, there is a lot of learning. Here are some of the models that we came up with. I am attaching the original model and some of the variations. I am even including an interesting model that my oldest son (a software engineer for Intel) created! The rest of the models are from my students - who gave permission to have them posted. I am happy to exchange ideas or answer questions with other teachers.
The Sarah workbook is set up so the allele frequencies from generation one become the beginning frequencies for generation 2 and so on.
The Jenna workbook is set to add 0.15 to the "p" allele each generation (but that value can be changed.
The Elizabeth workbook is set so that only a certain number of the BB genotypes survive in each generation. (That can be changed also)
The other workbook has two she
