Calculating Allele and Genotype Frequencies - Grade 11

Through this fully resourced lesson students will determine allele and genotype frequencies based upon the Hardy-Weinberg principle. This lesson requires students to have already been introduced to the Hardy-Weinberg principle and its conditions as well as the equation p+q=1 and what it represents.

Students will first determine how genotypes are represented by the Hardy-Weinberg principle (p2 + 2pq + q2 = 1). Students will then calculate a number of allele and genotype frequencies based upon exam style questions, worked answers are then provided for each question. Students will finish by applying their knowledge of the Hardy-Weinberg principle to more exam style questions.
