Found 11 resources for the concept: Evolution is often defined as a change in allele frequencies within a population

imageBreeding Bunnies
Students simulate breeding bunnies to show the impact that genetics can have on the evolution of a population of organisms.

Audience: 13-16

Resource type: Classroom activity

imageA Step in Speciation
Students compare different subspecies of a California salamander on a grid map of California to focus on patterns of their distribution, their likely evolutionary relationships, and probable sequence of formation from the ancestral salamander.

imagePea taste
This case study in the form of a set of PowerPoint slides examines the evolution of the wrinkled pea from its ancestral round pea shape.

Audience: 13-16

Resource type: Case study

imageThe Making of the Fittest: Natural Selection in Humans
This 14-minute film describes the connection between the infectious parasitic disease malaria and the genetic disease sickle cell anemia - one of the best-understood examples of natural selection in humans.

imageProblem-based discussion: Population genetics calculations and Hardy Weinberg
This set of two PowerPoint slides featuring questions for problem-based discussion (i.e., open-ended questions that engage students with each other and with course material) can be easily incorporated into lectures on populations genetics.

imageHigh altitude adaptations: The work of Emilia Huerta-Sánchez
This research profile follows statistician and population geneticist Emilia Huerta-Sánchez as she studies the adaptations that allow Tibetan highlanders to live 13,000 feet above sea level without developing altitude sickness.

imageThe Making of the Fittest: Natural Selection and Adaption
This 10-minute film describes the research of Dr. Michael Nachman and colleagues, whose work in the field and in the lab has documented and quantified physical and genetic evolutionary changes in rock pocket mouse populations.

imageThe Making of the Fittest: The Birth and Death of Genes
This 13-minute film describes how scientists have pieced together the evolutionary history of the Antarctic icefish by studying its genome — an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.

Audience: 13-16

imageDNA to Darwin: Lactose tolerance
Students analyze genetic data to discover which genetic variants are associated with lactose tolerance in different populations. A statistical test (chi-squared) is used to work out whether specific genetic changes have significant effects on lactase persistence.

Audience: 13-16

imagePopulation genetics, selection, and evolution
This hands-on activity, used in conjunction with a short film, teaches students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. It

This video and worksheet use real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle.
