Engage your students in hands-on learning with this interactive genetics activity that brings Punnett squares and Mendelian inheritance to life! In this modelling genetic crosses resource, students build and breed their own “Paper Mates”—fun paper characters with heritable traits such as eye color, arm length, hair texture, and footwear. This creative, student-led activity reinforces key biology concepts such as dominant and recessive genes, genotype vs phenotype, and the use of Punnett square
