With lesson objectives and outcomes, and a clear sequence of classroom tasks, including modelling activities, students will be able to use a genetic cross to show sex inheritance, use direct proportion and ratios in genetic crosses to predict outcomes and learn how to simplify ratios and use them to make complex predictions on inheritance outcomes.
