A good interactive Punnett square site that offers a tutorial in how to fill out the squares for genetics.

This site from Access Excellence provides a good description of Punnett squares. However, if you are a more hands-on, visual learner, you may want to find a few other resources with more examples.

[Free Registration/Login Required] This flipchart show students how to use a Punnett Square to introduce how homozygous and heterozygous genotypes are inherited and how they determine phenotypes.

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.

After watching video clips from the Harry Potter and the Goblet of Fire movie, students explore the use of Punnett squares to predict genetic trait inheritance. The objective of this lesson is to articulate concepts related to genetics...

Students will draw a model of a Punnett Square on the calculator and discover all possible combinations of Genotypes. They explore theoretical and experimental probabilities. They also collect data through experimental probability and...

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.

[Free Registration/Login Required] Students will use Punnett Squares to analyze how biological traits are passed on to successive generations.

[Free Registration/Login Required] In this lesson Punnett Squares are used to illustrate genetic possibilities. There are exercises and assessment questions to use with Activotes.

[Free Registration/Login Required] This flipchart presents the use of Punnett Squares to predict the outcome of a genetic cross. There are practice exercises as well as assessment questions for use with Activotes.

DNA from the Beginning offers a biography on Reginald Punnett and William Bateson. Includes pictures of both Punnett and Bateson.

Resource provides a discussion of Mendel's law of segregation with a focus on genotype, phenotype, alleles, heterozygous/homozygous, and 2 x 2 Punnett squares.

Article defines Mendel's law of independent assortment, provides examples, and takes a look at how it is used to make predictions. Also, discusses dihybrid crosses and 4 x 4 Punnett squares.

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

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.
