Allele Frequencies and Sickle Cell Anemia Lab
Students investigate how selective forces like food, predation and diseases affect evolution. For this genetics lesson, students use red and white beans to simulate the effect of malaria on allele frequencies. They analyze data collected from the experiment and answer analysis questions at the end of the lab.

Fancy Fish: Gene Frequency
High school biology learners simulate gene flow within a population of fish. They hold colored fish cards as identification and carry "Good & Plenty®” candies to represent alleles, the recessive homozygous of which is lethal. You will need to construct the fish cards and set obstacles up around the room for fish to swim around.

Students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. They run a series of simulations varying allele frequency and population size and then analyze their data and propose a model to explain their results.

Roger Rabbit's Family ~ A Study of Population Genetics
Here is a cute, yet practical assignment for using the Hardy-Weinberg principle for determining allele frequency in an imaginary family of rabbits. Roger Rabbit, an albino bunny, noticed that some bunnies in his clan had brown fur. Your junior geneticists examine the genotypes for 200 members of the clan and calculate frequency.

Molecular Approaches to Evolution
Students examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and assess historical continuity among closely and distantly related species.

Measuring Evolution of Populations
The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of characteristics of populations.

Measuring Evolution of Populations
The Hardy-Weinberg principle is the focus of this concise slideshow. Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W principle are shown applied to sickle cell and malaria.

Evolution of Populations
In this evolution worksheet, students look at the role genes play in the transferring of traits to generations. Students review gene pools, natural selection, and genetic drift. This worksheet has 5 fill in the blank and 15 multiple choice questions.

Population Genetics and Informatics
For advanced biology learners, here an interesting presentation on Alu elements within a population. It begins by teaching viewers how to perform calculations for alellic and genotypic frequencies. The second half of the slide show walks them through the use of an online allele server.

Hardy Har Har: Investigating the Hardy-Weinberg Principle
Well, shiver me timbers! Biology pupils practice using the Hardy-Weinberg principle for computing change in gene frequency within a fictional population of pirates. The genetic trait being analyzed is the presence of sea legs, legs that prevent them from falling over when the ship is tossing.

Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all the difference in survival when the landscape changes drastically.

Again, the basis for trait inheritance and the impact of alleles in phenotypes was covered in previous videos. This presentation focuses on gender and the likelihood of traits if they are sex-linked. Sal tells a great anecdote about where the blame should have been placed for Henry VIII's female offspring.
