This activity begins with sections that help students to understand basic principles of genetics, including (1) how genotype influences phenotype via the effects of genes on protein structure and function and (2) how genes are transmitted from parents to offspring through the processes of meiosis and fertilization. Then, a coin flip activity models the probabilistic nature of inheritance and Punnett square predictions; this helps students understand why the characteristics of children in many real families deviate from Punnett square predictions. Additional concepts covered include polygenic inheritance, incomplete dominance, and how a new mutation can result in a genetic condition that was not inherited. This activity helps students meet the Next Generation Science Standards.

In this hands-on, minds-on activity students use model chromosomes and answer analysis and discussion questions to learn how the cell cycle produces genetically identical daughter cells. Students learn how DNA replication and mitosis ensure that each new cell gets a complete set of chromosomes with a complete set of genes. Students learn why each cell needs a complete set of genes and how genes influence phenotypic characteristics. Finally, students analyze exponential growth to understand how a single cell develops into the trillions of cells in a human body. This activity helps students meet the Next Generation Science Standards.
