I created this as a review for my 7th grade Life Science students after we did a genetics unit (but before the test). I had originally posted the "answer key" so students could check their answers. I found, however, that the students who were struggling were simply copying the answers. So, I came up with idea that they could work through the problems and the answers are "posted as QR" so they can't get out their iPads or phones until I see they have worked through the problem. As they check through, I have them fill out the bubbles so I can easily walk around and spot check who gets it and who needs extra help. Stay tuned for my other QR lessons. This set includes "regular" Punnett square scenarios as well as codominance and incomplete dominance. I made them on separate pages so that you can print or not print what you need or don't need. I also made it so you could print in color or black and white with no changed result as far as student understanding. I hope you enjoy.
