Students investigate the principles of probability that can be used to predict hereditary traits.

Eighth graders become familiar with Punnett squares, specifically purpose, application and interpretation. Key terms from previous lessons (included below) are reviewed/reinforced before data is applied to a Punnett square and interpreted.

High schoolers assess some common inherited traits which are easily observable and note their phenotype for the trait. Students compare their phenotypes to those of their parents and attempt to describe the pattern and manor of inheritance.
