This activity allows students to work through a series of games to learn about DNA, protein bases, and how they combine, dominant and recessive genes, Punnett Squares and genotypes, and phenotypes. 

Biology students often struggle to understand how it can be that the same two parents will produce genetically different offspring. This lab exercise is a very visual way to demonstrate the "making of a monster" one gene at a time. The resources include a full sheet of vocabulary and instructions, plus a data table to record the crosses. For advanced students, you can take the activity further with a sheet of follow up questions.
