Upper level discussion of several of Mendel's experiments and laws.

This interactive activity, adapted from the Dolan DNA Learning Center, uses Punnett squares to illustrate Mendel's laws of inheritance and how a particular gene combination results in a 3-to-1 ratio of dominant-to-recessive traits.

A great supplement to help introduce Punnett Squares. It tells how to set them up and how to use them correctly. A sample quiz is offered and feedback is given to help with understanding why an answer is correct or not.

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...

This lesson is adapted from a Connected Mathematics Unit, How Likely is It? This investigation introduces biology as a source of applications for probability. In this lesson, Curling your Tongue, young scholars determine how many...

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...
