genetics

The activities in Genetics help students to understand the basic principles of genetics, including concepts of recessive and dominant alleles, relationships of phenotype to genotype, Punnett squares, and pedigree analysis. The introductory section on inheritance of albinism demonstrates how understanding meiosis and fertilization provides the basis for understanding inheritance and Punnett squares. The next two sections, Coin Toss Genetics and analysis of class data on the sex makeup of sibships, help students understand the probabilistic nature of Punnett square predictions. The final activities analyze the genetics of sickle cell anemia and pedigrees for families with albinism and achondroplasia.
