2. Put the cursor over an organism to view its genotype
3. Pick two organisms with known genotypes, predict the results, cross them, and see if you're right
4. Repeat (3) until you're sure you understand the model and how it works
• Click "New Graded Problem" to get a problem to try.
1. Try to solve it by carrying out crosses and observing the results
