Gregor Mendel's work revolutionized agriculture from an art to a science. Explore Mendel's work with an interactive lesson that includes animations, video, and practice problems. The instruction describes the early discoveries that...

Dominate a lesson on genetic traits. Young scholars learn about the difference between dominant and recessive traits with an interactive lesson. An animation demonstrates Mendel's work on the inheritance of traits, and interactive...

Rules are not meant to be broken in genetics. Scholars learn to build Punnett squares to track the inheritance of dominant and recessive traits in an interactive animation activity. Online questions help individuals reflect on their...

Yellow and blue make green—unless you're studying the inheritance of genetic traits. An interactive lesson explains the difference between blended traits and pure traits and gives examples of their occurrence. The resource includes a...

Frederick Sanger won two Nobel prizes for protein sequencing and DNA sequencing. Young scientists learn about Dr. Sanger's research and amazing discoveries. They read an article and a biography, view videos and animations, and apply...

Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

Mendel was the first to look at individual traits within a species. Step in his shoes as an interactive lesson takes users through his journey. An animation describes the design of his experiments and how he isolated individual traits to...

How do genetics gurus know so much about gene expression? See traits materialize before your very eyes using a presentation with embedded simulations. Science scholars develop an understanding of the techniques used to follow the work of...

Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....

Connect Mendelian genetics with Darwinian theories. An interactive lesson lets pupils explore how George Shull used research from other scientists to explore genetic variation. The resource outlines the statistical analysis of genetic...

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

An interactive Punnett Square calculator which allows students to work out patterns of inheritance for any autosomal recessive genetic trait or disease.

Mutation is a process that changes a DNA sequence. But how does a difference in a gene's DNA sequence (or genotype) lead to a difference in an observable trait (or phenotype)?

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.
