One of the essential skills in genetics is learning to apply what you know to new situations. On the following website there are 13 monohybrid cross problems to analyze. For now, you should only consider problems 1–8. Each problem is designed to have you take a fact or discovery you’ve read about and apply it to a new situation. As you work through each problem, notice that there is a link to help or to a tutorial from within each one. These are excellent review links, and you may use them often if you find that you are stuck. Follow the link below to the index and work through problems 1–8.
