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 Punnet squares to
predict ways genes can combine during fertilization.
Class size - 40 students.
