Eighth graders interpret the genotypes and phenotypes, then pair up chromosomes.

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...

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.

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

Instructional module focusing on Gregor Mendel's scientific legacy and analysis of multiple genetic traits. Discussion includes Mendel's work on his second law, the Law of Independent Assortment, which states that different traits are...

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

A collection of genetic learning activities provides an engaging way to learn about traits, or better understand disease risk.

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...

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.

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...

[Free Registration/Login Required] An informational text about learned and inherited traits. A question sheet is available to help students build skills in reading comprehension.

Learn how the genes inherited from two parents can be recombined in their offspring in this simulation activity. In addition, investigate the probabilities of passing on inherited genetic disorders.

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

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.

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...

Through a series of videos and narrated animations, learn how evolution affects gene expression in species. Find out how visualizing gene expression can help explain what a specific gene does.

An interactive Punnett Square inheritance calculator helps students work out patterns of recessive inheritance for a trait, such as straight or peaked hairline.

[Free Registration/Login Required] Students read about genetic similarities and differences among butterfly species. A question sheet is available to help students build skills in reading comprehension.

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 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.

A tutorial reviews polygenic and multiple alleles, Punnett Square, sex-linked trait, and inheritance patterns. Follow the slides to ensure comprehension of inheritance.

This site explains genetic beliefs before and after Mendel, and also includes a section on Mendel himself and his experiments, entitled, "The Monk and his Peas".

In this lesson students create imaginary creatures, called "Reebops," to explore the relationships between genes and inherited traits. Using Reebops as a model, students learn how hereditary information is passed from one generation to...

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...
