Classroom Snapshot
What Students Learn
Students distinguish genotype from phenotype and use a Punnett square to model inheritance probability.
Students investigate how two purple-flowered parent plants can produce a white-flowered offspring.
How the Lesson Teaches Before It Assesses
Students first learn dominant and recessive alleles, genotype, phenotype, and gamete splitting with examples before building the Punnett square.
Core Student Actions
- Sort traits by appearance and allele letters
- Build parent gametes
- Complete a Punnett square
- Use the model to explain offspring outcomes
Why This Is More Than a Quiz
The activity starts from a genetics mystery and builds the model step by step rather than beginning with a bare Punnett grid.
Privacy and Classroom Use
The interactive lesson runs in the browser without student accounts, names, emails, analytics, or cloud storage. Teachers can project it, assign it directly, or pair it with optional print materials.
