Punnett Squares

Inheritance Patterns: Punnett Squares

Recently, my class was finishing up the unit on genetics and learning how to do a variety of punnett squares  and  I knew I needed to create a better way to review this concept.

So… I created this Punnett Square Challenge that my students love.

Prior to completing this punnett square activity, students should have had exposure to examples, of complete dominance, incomplete dominance, co-dominance, multiple alleles and dihybrid crosses.

After students have had some practice with  punnet squares, this activity will serve as a review or a great gauge for \their understanding of the content.

In this activity,  students will complete each punnett square (1 through 6) in order.

Student will only receive one punnett square at a time and will only get the next one when they have correctly completed the preceding punnett square.

I have found that students generate great conversation when working together to complete these punnett squares, although it can be done independently.

Each new punnett square will add a degree of difficulty as they progress through the activity. I walk around with folders that contain the problems. As they get them correct I give them the next problem.

If students complete the activity within  first or second I offer them a homework pass or bonus points. I have done this as a race and timed and both way worked well. The homework pass incentive takes their effort up a notch.

Student always enjoy this and the discussions that take places are amazing.
