Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

Two fish appear different, but how do scientists determine their genotypes? Scholars practice performing test crosses to determine the genotypes of fish given their phenotypes. They answer in-depth comprehension questions and complete...

The proteins inside a cell determine the shape of the cell. While most red blood cells have a circular shape, those with sickle cell take the shape of a sickle. This change in shape causes multiple issues in the system. Scholars solve...

Around half of the states in the US ban first cousin marriage, but does science support that ban? Scholars work through genetic analysis of the risks to understand if more states should ban the practice—or if some should remove it. They...

Did she cheat on her husband? Did the hospital switch the babies? Should they have children? As much as this sounds like the plot for a soap opera, all of these questions fit into a single lesson on genetics. Scholars read about three...

Taboo, anyone?! A vocabulary review lesson asks learners to give their partners clues to help them guess the target word. The catch? There are words that are taboo. If they use the prohibited words, they don't get credit if partners...

A simulation where students flip coins to mimic how parents pass genetic traits to their offspring through heredity. This activity also illustrates the difference between dominant and recessive genes, and how they interact with each...

First, students toss coins to determine what traits a set of mouse parents possess, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents...

This set of seven activities will proved a thorough review of Mendel's work. The interactive experiments are easy to follow and drive home the concepts.

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.
