Lab 8: Population Genetics & Evolution

Collect and analyze data of readily observable genetic traits!
Your students will determine the phenotype, genotype and frequency of easily observed human traits. Then they'll identify the dominant
and recessive genes for each trait. With the class as a sample population, your students will use a variety of taste test papers to determine the percentage of individuals who can detect a unique taste. They'll then apply the Hardy-Weinberg Principle to calculate the allele frequencies for this trait and compare their class data with an ideal population. In the second part of this lab investigation, your students will use allele cards to model allele frequency change in an ideal population, a population on which selection is acting, an example of
heterozygote advantage and as a result of genetic drift. The investigation includes detailed coverage of natural selection, the Hardy-Weinberg equation and other related topics to better prepare your students for the AP final exam.
