Hardy-Weinberg principle (CIE International A-level Biology)

This fully-resourced lesson guides students through the use of the Hardy-Weinberg equations to determine the frequency of alleles, genotypes and phenotypes in a population. Both the detailed PowerPoint and differentiated practice questions on a worksheet have been designed to cover point 17.2 (d) of the CIE International A-level Biology specification which states that students should be able to demonstrate and apply their knowledge and understanding of the use of the principle to calculate frequencies in populations.

The lesson begins by looking at the two equations and ensuring that students understand the meaning of each of the terms. The recessive condition, cystic fibrosis, is used as an example so that students can start to apply their knowledge and assess whether they understand which genotypes go with which term. Moving forwards, a step-by-step guide is used to show students how to answer a question. Tips are given during the guide so that common misconceptions and mistakes are addressed immediately. The rest of the lesson gives students the opportunity to apply their knowledge to a set of 3 questions, which have been differentiated so that all abilities are able to access the work and be challenged.
