Now that you have explored a little about genotypes and phenotypes in the previous model, you have more control over setting genotypes and thus, the phenotypes of the parents. 

Play more with the model, test your own understanding from the previous explorations and investigations. 

Make some predictions about genotypes and phenotypes of the offspring, before you MAKE-F1-GENERATION.  

Design puzzles for others regarding the inheritance of traits using this model. Share those in the comments section.
