Seventh graders describe the basic structure of the DNA molecule. They identify what an inherited trait is and how it can be determined by one or more genes. Finally, 7th graders identify that plant and animal cells contain several...

In this genetics worksheet, high schoolers access a given website, chose a genetic disorder, and complete the 10 short answer questions about the disorder.

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.

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

Explains what dominant and recessive traits are and how they work, and provides a list of single gene traits with the degree of manifestation if they are dominant or recessive. Also discusses co-dominance, incomplete dominance, polygenic...

In the real world, genes often come in many versions (alleles). Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance.

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...

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...

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...

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

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...

In this activity, students simulate a Punnett square of a cross between two heterozygous individuals and produce a histogram. They compare actual and expected results of genetic crosses.

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...

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.

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...

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.

Take this 9-question unit test over classical genetics.

This is a ten-question quiz pertaining to Mendelian genetics.

Understand the basics behind Mendelian genetics.

A site with information about the hereditary patterns in the science of biology including dominant and recessive genes, alleles, the Punnet square, examples, and interesting facts.

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...

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...

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.
