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.

At this site see an online visual of meiosis, fertilization, and inheritance and play a game.

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...

Photos of slides and genetics charts accompany the text and explain the differences between sickle cell train vs. sickle cell anemia, symptoms of sickle cell disease, secondary diseases/conditions associated with sickle cell, mechanism...

[Free Registration/Login Required] Students engage in the concept of natural selection and further their understanding of diversity and relatedness within the living world. Inquiries into evolution explain the ways in which natural...

Some characteristics, like the shape of your hairline, whether your earlobes are attached or detached, and whether or not you have freckles are inherited from your parents. In this science project you will learn about Mendelian traits,...

This instructional activity is adapted from a Connected Mathematics Unit, How Likely is It? This investigation introduces biology as a source of applications for probability. In this instructional activity, Curling your Tongue, students...

This site is provided by the University of Arizona and it gives great information on the subject. Good collection of dihybrid crosses which exemplify the issue of independent assortment. Work these once you think you've mastered th concept.

This site, which is provided for by the University of Arizona, gives problems online that correspond to basic Mendelian genetics. Test your knowledge once you've read about Mendel and accessed the links to the various subjects covered in...

This resource explains Mendel's first law (Law of Segregation) in detail. Includes Mendel's original experiments with results and conclusions.

Mendel's second law and how he arrived at it through his experiments. Includes vocabulary and examples.

This personal site gives the seven characteristics that Mendel observed and a fairly large background to what Mendel saw and interpreted.

Good description of Mendel's findings and his second major principle.

Using chromosome and gene models, students play the roles of two parents in this genetics simulation. The object is to create four offspring and determine their genotypes and phenotypes, and determine the probability of having offspring...

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...

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...

Historical perspective on Mendel's contribution. Spends a little time setting up what the current beliefs of Mendel's day were and how he changed things with what he did.

Explains and gives examples of polygenic inheritance.

You have probably seen figures showing how human beings are related to chimpanzees, gorillas, and other primates. In this genomics science fair project, you will use bioinformatics tools to generate your own primate family tree.
