A two-page instructional activity provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares,...

Two individuals share 99.9 percent of their genetic codes, yet diversity is observed everywhere. Young scientists learn about diversity through hands-on activities and an experiment. They apply the concepts of independent assortment and...

What do you get when you cross a purple with a white? Genetics geniuses figure it out with a Punnett square. On this assignment, they must solve crosses for incomplete dominance, codominance, lethal dominance, and sex-linked genes. It is...

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

Can we find the phenotypes and genotypes of magical ability for the characters in Harry Potter? Of course, but first we need to understand incomplete or blended dominance, co-dominance, multiple alleles, and regulatory genes. This...

Students explore the principles of incomplete dominance and codominance in genes. They apply genetic previously discussed genetic principles to determine solutions to inheritance problems including multiple alleles, incomplete dominance...

In this short space, it would be impossible to describe the breadth of this seven-page genetics worksheet. Geared toward AP or college biology learners, they explore not only the basic vocabulary and concepts, but also the Law of...

Did she cheat on her husband? Did the hospital switch the babies? Should they have children? As much as this sounds like the plot for a soap opera, all of these questions fit into a single lesson on genetics. Scholars read about three...

Harness young scientists' knowledge of genetics with an engaging science activity. Students start by flipping a coin to determine the genotypes and phenotypes of two parent monsters, before using Punnett squares to...

Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

A three-page quiz about genetics, which includes Punnett squares, blood types, questions about Mendel and his contributions, and vocabulary comprehension. Use this for a study guide, a pretest/post-test, or a note-taking learning...

In this genetic disorders worksheet, students complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.

Students solve a crime by matching a suspect's blood type to physical evidence collected at the crime scene. In this forensic science lesson, students identify the different blood types. They explain how blood tests work.

Students review the concepts of incomplete dominance, co-dominance and multiple alleles. As a class, they are introduced to the concept of sex-linked genes and how they are passed to offspring. To end the lesson, they examine possible...

Students examine Punnett squares charts and analyze how they are used for successful breeding and predictions of certain traits. They complete interactive Punnett square charts, quizzes, problems, and concentration games.

Students identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.

Students differentiate phenotypes and genotypes. In this genetics lesson, students complete the punnett square. They design their own baby by choosing the phenotype they want.

In this science worksheet, students find the answers to various types of heredity problems. They use the sheet to set goals for completing the unit.

Fourth graders study sickle-cell anemia.

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.

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...

Explains what codominance is in heredity, and what it looks like in humans, animals, and plants.

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