The learning connection
The Punnett square makes genetic probability visible as a grid that can be physically filled — converting an abstract statistical prediction into a spatial, manipulable artefact. Students who fill in Punnett squares by hand for their own traits build ownership of the concept that pre-filled textbook tables cannot create.
Try it with your learner
1. Write Tt x Tt cross. 2. Fill Punnett square. 3. Count phenotype ratio. 4. Try TtYy x TtYy.
