Butterfly Distribution  
Previous | Main Page | Next

Now you can look at a more realistic distribution of offspring. Choose the parents and the number of offspring you would like. This model has a random element built in so that the ratio of genotypes will be close to that predicted by a Punnett square but not exact. Is this more realistic?

When you have mastered this, try working the Punnett square backwards by moving to the next model.
