Mendelian Genetics Unit: Lesson 6: Intro to Punnet Squares

Before students can continue their monster project, they need to learn how to organize information about alleles, and predict future offspring using Punnet squares!

This lesson focuses on how to organize information without a Punnet square, and looks at the pros and cons of solving a different way, then shows the more streamlined Punnet squares with side by side comparisons so students can see the exact same information is in both.

There are levels of practice problems ranging from simple (filling out punnet squares with given genotypes and phenotypes) to difficult (story problems where students determine their own genotypes from the problem, and predict fractions and percentage amounts for future offspring), as well as guided notes.
