Population genetics is the study of genetic variation in populations. This simulation allows the user to observe the frequencies of two alleles over time.

This is a group of Mendelian Genetics exercises that are designed to show the evolution of a trait within a population. The site covers instruction in calculating genotypic and allelic frequencies, determining dominance, the...

A collection of articles on evolutionary genetics focusing on the topics of phylogenetics, mutation and molecular population genetics, the genetics of speciation, genome evolution, and evolution and development. Learn how to read a...

This video segment from NOVA: "Cracking the Code of Life" explores the genetic similarities and differences among organisms.

Explains what genetic drift, gene flow, and natural selection are, and compares their differences, two at a time.

This site from Palomar College discusses the concepts of genetic drift and founder effect. Provides some specific examples of the founder effect and a discussion of these.

Laurence Moran discusses one of the most important mechanisms of evolution, Random Genetic Drift.

Discusses conditions needed for the Hardy-Weinberg Law to hold true and demonstrates calculations involving allelic frequencies to illustrate this principle.

How natural selection works at the level of genes, alleles, genotypes, & phenotypes.

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

This lesson plan requires students to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

Take a closer look into the modern view of evolution. This article includes many pieces of evidence, all which support the theory of evolution.

Today, about one-tenth of the world's population are southpaws. Why are such a small proportion of people left-handed -- and why does the trait exist in the first place? The following video investigates how the uneven ratio of lefties...

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents...

Discusses the historical background leadingto the development of the Hardy-Weinberg principleand the assumptions of the principle. Providesmathematical and graphical illustrations ofthis principle.

This site explores what Hardy-Weinberg Equilibrium is, and how teachers can explore this topic in their classrooms. Content includes background information on this topic, as well as numerous learning activities.

A team of scientists studied the schooling behavior of threespine stickleback fish by experimentally testing how individual fish responded to an artificial fish school model.
