Lesson Summary: Hardy-Weinberg Equilibrium According to Hoyle

Lesson summary for... Hardy-Weinberg Equilibrium According to Hoyle Author/Source: Cronkite, Donald

Overview:	Students achieve an understanding of the Hardy-Weinberg Equilibrium by using decks of playing cards without recourse to algebra.
Concepts:	This lesson covers the following concepts: New heritable traits can result from recombinations of existing genes or from genetic mutations in reproductive cells. Natural selection acts on phenotype as an expression of genotype. Populations evolve. Evolution may occur as a result of genetic drift. Speciation is the splitting of one ancestral lineage into two or more descendant lineages.
Grade Level:	9-12
Time:	One class period.
Teacher Background:	Explore these links for additional information on the topics covered in this lesson: Genetic Variation Natural Selection
Teaching Tips:	As it is written, the exercise requires an understanding of the basic vocabulary of Mendelian genetics. Extensions provided will facilitate the understanding of genetic drift, Founders effect, and bottle necks. Discussion is critical, as it is difficult to simulate selection without being misleading.
