[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...

An introductory lesson on the basics of heredity, and the inheritance of genetic traits. [7:57]

Play the role of a scientist and piece together the genetic puzzle to determine the gene responsible for a disorder.

[Free Registration/Login may be required to access all resource tools.] Discusses linked genes and why some characteristics are inherited together.

This is a technology-based, hands-on Biology lesson on Heredity and Traits. Students learn about the basics of Heredity through a virtual tour and then work to create their own dragon based on the inheritance of traits.(Adapted from ASIM).

Article reviews Mendel's basic model of inheritance then provides an overview of variations on Mendel's laws, including multiple alleles, incomplete dominance, co-dominance, pleiotropy, lethal alleles, sex linkage, genetic interactions,...

This problem set is based on a question received from a woman with red-green color blind as well as other members of her family. She wanted to know if we could help her understand how she inherited her color blindness.

This site explains the X-linked inheritance of Hemophilia and includes a diagram.

Learn about Thomas Hunt Morgan's experiments with the fruit fly (Drosophila melanogaster) as a model system.

A virtual world where students conduct genetics experiments on a model species called drakes. After the story narrative is introduced, they engage in a quest to heal a sick dragon. As they play, they will learn about the principles of...

This ebook discusses the topic of human pedigree analysis, a type of genetic science used to determine inherited characteristics.

A web-based course which allows students to explore the fields of genetics and genomics. The three course modules are transmission genetics, the nature of genetic material, and medical genetics and genomics. Use of this resource requires...

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...

Read about the PTC gene, and listen to scientists discuss this accidental discovery which lead to important clues about human evolution.

This animated lesson will explain how genes are inherited in pairs, one from the mother and one from the father.

At DNA from the Beginning, choose from classical genetics, molecules of genetics, genetic organization and control. Each concept is explained through animation, an image gallery, video interviews, biographies and links.

Turn the control knob in this interactive to change the level of gene expression in a cell. Find out how gene, mRNA, and protein production are linked.

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.

(Requires Microsoft PowerPoint or OpenOffice Impress.) This presentation discusses the goals of pedigree analyis and uses example of how the process is performed.

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...

In this lesson, 5th graders learn about basic genetics and how genes can affect someone's behavior. They will write their own narrative about a character they create as a class in order to illustrate the effects of inherited traits and...

Student teams research human behavior and explore whether traits are inherited only by genetic inheritance or if environmental factors can play a role as well.

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 Science game about genes was created using the What2Learn game machine. The objective of the game is to correctly answer the questions about genetics. Students should learn genetics and heredity before playing the game.
