Human-Genetics: A Worldwide Search for the Dominant Trait allows you to collect data and share your results with students around the world. Register your class, complete the student survey, participate in discussion boards, and interact...

[Free Registration/Login may be required to access all resource tools.] Another exception to Mendel's rules is polygenic inheritance, which occurs when a trait is controlled by more than one gene. This means that each dominant allele...

A three-day unit introduces heredity by helping students identify their own genetic traits and then leading them in an exploration of generational traits and variation. Find printable worksheets, data tables, and graphs, as well as...

This site explains how to determine the chances of inheriting certain traits from our parents. It gives mathematical examples and exercises.

Fifth graders will discover the difference between inherited traits and learned behaviors by bringing the traits to life in a game of charades. After that, the students will demonstrate knowledge of recessive and dominant traits as they...

There are many ways to learn about Gregor Mendel and his pea experiments. This interactive tutorial requires users to actually plant, grow, and cross different plants to observe their traits. Pedigrees are also used to help show dominant...

Breed pure mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Punnett squares can be used to predict results. (Free usage is limited to five minutes...

This site, which is provided for by the University of Arizona, gives an interactive genetics problem dealing with co-dominance. Links are provided throughout this site for additional information on related subjects.

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

Find out what happened when Mendel crossed two hybrid pea plants. The animations do a good job explaining why these crosses produce a 3:1 ratio of traits.

Manipulate the environment to see how it plays a role in the rapid evolutionary changes in rock pocket mice.

Clermont College provides a good interactive practice test using Punnett squares.

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...

[Free Registration/Login may be required to access all resource tools.] Covers Mendelian inheritance of autosomal and sex-linked traits in humans.

Explore the genetics of plants discovered by Gregor Mendel in the nineteenth century. These interactives will walk users through the planting and growth of pea plants, possible combinations of plans to alter traits, predict the results...

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, 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...

Take this 9-question unit test over classical genetics.

This article from DNA from the beginning is loaded with goodies about genetics and DNA. Starting with Mendel all the way through the concept of DNA, you will see how life is given certain characteristics. Some animations and audio clips...

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 from Palomar College provides an online practice quiz includes history as well as some of the genetics. Includes feedback. A great learning and practice site.

[Free Registration/Login may be required to access all resource tools.] In all of Mendel's experiments, he worked with traits where a single gene controlled the trait. Each also had one allele that was always dominant over the recessive...

This site, which is provided for by the University of Arizona, gives an interactive problem on blood type, which is an example of codominance. Links are provided to access the various subjects covered in this problem set.

A simple slide show from a lecture on genetics showing how blood typing shows codominance.
