In this module, students explore how traits are passed from parents to offpring and how inheritance patterns can be used to predict possible outcomes. Students begin by building rabbits with randomly selected maternal and paternal trait tiles, then compare the traits that appear across the class. Students learn how alleles, dominance, genotypes, and phenotypes explain patterns of inheritance and use Punnett squares to model possible offpring traits. Students will learn that offpring inherit alleles from both parents, and that probability can be used to predict possible genotypes and phenotypes, but not guarantee the traits of any individual offpring. An optional mini-lesson on dihybrid crosses allows teachers to deepen or diffrentiate instruction based on district needs.
