Population Genetics
Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

The Making of the Fittest: The Birth and Death of Genes
Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Genetic Drift
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...

Recombination and Pedigrees
Biology aces answer four questions about genetic recombination and nine questions about pedigrees. This worksheet is very focused on these two topics. Most of the pedigree questions relate to the genetic disorders, Alkaptonuria and...

Color Variation Over Time in Rock Pocket Mouse Populations
While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

How Novel Icefish Genes Can Improve Human Health
Designed to accompany the 13-minute video The Making of the Fittest: The Birth and Death of Genes, this handout serves as both a viewing guide during the video and an analysis of how the adaptations of the icefish might help treat some...

Chromosomes and Genetic Mapping
Students create models of chromosomes using clay, coins, beads, or marbles. They complete a worksheet regarding their crossover frequencies they created with their chromosomes and gene models. They read an essay on sex chromosomes and...

Lactase Persistence: Evidence for Selection
What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...
Curated OER
Chromosomes and Genetic Mapping
Students are introduced to mapping by crossover frequency. Genes travel as packaged trains on chromosomes. They use this experiment, genetic mapping assignment, that allow students to quickly complete the assignment and yet examine the...

Inherited Traits
Students work with a partner to complete an inventory of their traits and compare and discuss their unique qualities. In this biology lesson, students determine percentages for the frequency of observed traits of classmates, compile the...

Molecular Approaches to Evolution
High schoolers 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...

Using Molecular and Evolutionary Biology to Understand HIV/AIDS and Treatment
HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...
