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

Take this interactive quiz over Mendelian and molecular genetics, then review your score and any missed questions at the end.

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,...

Explains and gives examples of polygenic inheritance.

An animated pedigree clearly explains the way hemophilia was inherited in the Romanov family. Interpreting pedigrees and sex-linked crosses should be much easier to understand after going through this tutorial.

In this activity, you will use an alien model to demonstrate how genes or physical traits are passed on from parents to their offspring.

Find out how epigenetic tags that tell genes whether to turn on or off in their lifetime, act as a cellular memory.

Get it all straight! The "Tour of the Basics" will help clarify the basic principals of genetics science from DNA, genes, chromosomes, proteins, heredity, and traits.

Explains basic genetics concepts, including genes, DNA, chromosomes, sex chromosomes, how traits are inherited, genetic variation, cloning, and stem cells.

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

An indepth introduction to genetics as a whole with sample lessons, vocabulary, and bibliography. From the Yale-New Haven Teachers Institute.

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.

Geniventure engages students in exploring heredity, genetics, and the protein-to-trait relationship by breeding and studying virtual dragons. Students play through six levels of challenges, conducting simulated experiments that generate...

Learn about the development of transgenic animals and some potential applications. The field of transgenic animals is very young and still has many hurdles to cross.

An introduction to heredity and genetics. Learn about how physical traits and other qualities are passed down to people from their parents.

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...

This lesson will give examples of disorders that are linked to genes on the X chromosome.

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.

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...

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...

A useful introduction from the Oak Ridge National Laboratory on the study of how genetics and behavior are linked. Many useful resource links are included.

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

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