This set of videos takes the view through the logic, process and terms involved in using Punnett Squares. The first video is to be used as a discussion piece to see what students might already know about Gregor Mendel. His work and life are then discussed. The terms genotype, phenotype dominant allele and recessive allele are defined. The steps of making a Punnet Square are shown. Next, "The Law of Independent Assortment" is discussed and the steps of completing a dihybrid cross are shown. Next, link genes and sex linked traits are defined. At the end of this list, genetic mutations and reading a pedigree chart are described. (NSES Science Content Standard C grades 9-12 - Life Science)
