This is a group of Mendelian Genetics exercises that are designed to show the evolution of a trait within a population. The site covers instruction in calculating genotypic and allelic frequencies, determining dominance, the...

Explore the connection of genes and enzymes in regards to heredity and genetics. Concepts associated with dominant and recessive traits are also presented.

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...

Instructional module focusing on Gregor Mendel's Laws of Inheritance. Discussion includes Mendel's discovery of dominant and recessive traits as well as co-dominance and incomplete dominance in genetics. Site also includes an interactive...

This interactive activity, adapted from the Dolan DNA Learning Center, illustrates how Gregor Mendel used purebred yellow and green peas to show that some genes are dominant and others are recessive.

Students learn about patterns of inheritance including genotype and phenotype, and then learn about the inheritance of autosomal dominant and recessive and sex-linked genetic disorders.

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

The basic principles of genetics are in this effective site. Gender determination, recessive traits, and the Punnet Square are the topics examined. There is also a Punnet Square practice exercise to assess your comprehension of the...

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 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.

Read about phenylketonuria and the tests used to diagnose it in those who might have inherited this recessive trait.

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.

Thomas Hunt Morgan will explain the research he did to determine that some traits are linked to the sex of an individual.

In a class discussion format, the teacher presents background information about basic human genetics. The number of chromosomes in both body cells and egg and sperm cells is covered, as well as the concept of dominant and recessive...

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...

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...

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

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

[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...

Students will explore Gregor Mendel's laws of genetics in this lesson. Students will be paired in male and female groups. If girls and boys can't be evenly divided, same sex students can be paired to represent research scientists....

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

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.

This site from Palomar College provides a good background on exactly what Mendel did. Vocabulary links throughout make this a very good introduction article for genetics.
