Description

Challenge your students to determine the phenotype, genotype and frequency of easily observed human traits and identify the dominant and recessive genes for each trait. With the class as a sample population, students use a variety of taste test papers to determine the percentage of individuals who can detect a unique taste. They then apply the Hardy-Weinberg Principle to predict the allele frequency of this trait's gene and compare the estimate with their sample results. Additionally, students can construct and analyze a family pedigree for a selected trait, learning how it may be passed from one generation to the next. They also learn to use Punnett squares to predict ways genes can combine during fertilization.
