Incomplete Dominance Teacher Resources

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,...

Have you ever met twins or biological siblings with different skin colors? It's not unusual and a helpful video explains why. It includes incomplete dominance, codominance, polygentic traits, and Epistasis, and even explains...

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...

The instructor in a biology video defines and shows examples of incomplete dominance, codominance, epistasis, and multiple alleles. Viewers then explore Thomas Hunt Morgan and his crosses showing the discovery of gene linkage via fruit...

This PowerPoint jumps right into the details of unusual traits and how they are coded.  The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of...

Any pattern of inheritance that does not follow Mendel's laws uses non-Mendelian inheritance. The video explains this type of genetics with many guided practice problems. It covers incomplete dominance, codominance, and sex-linked traits.

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...

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 biology worksheet, learners use the information given about genetics and Sponge Bob to complete each section of the sheet. They identify and explain incomplete dominance and use it to help them complete the questions that follow.

A survey of Mendelian genetics is presented through this handout. Biology prodigies answer questions about the Law of Segregation, phenotypic ratios, and dominance. They define genetics vocabulary terms and describe various genetic...

The topics in the previous video about dominant and recessive traits are continued here as Sal Khan explains incomplete dominance, the randomness of genotypes and phenotypes, and covers how to calculate probabilities using Punnett...

Students draws the child's face and compares "mother's" and "father's" perception of characteristics. One student draws the child's face; partner writes a biography of the child at age 30- what is the child like, what have they...

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...

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

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...

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...

Students participate in an activity where they flip coins to determine which allele they pass on to the F1 generation and draw the resulting child's face. They identify several inheritance patterns including dominant, recessive,...

Nine lessons makeup a unit designed to reinforce grammar and vocabulary through practice pages based on readings of African folktales. Each lesson consists of a mini lesson, a vocabulary review, and a instructional activity. Topics...

In this basics of genetics worksheet, high schoolers review the concepts of genetic inheritance by writing the alleles for genetic traits inherited in offspring. They identify dominant and recessive traits given allele pairs, answer five...

In this genetics worksheet, students answer a variety of questions about genotypes, phenotypes, genetic inheritance, and traits. They solve for the probability of genotypes and phenotypes of offspring by completing monohybrid and...

In this biology learning exercise, 9th graders determine whether it is possible for two alleles to produce four genotypes. Then they state how many alleles there are for blood type. Students also determine which blood type is inherited...

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...

In this heredity worksheet, students will complete a graphic organizer with information relating to heredity, incomplete dominance, selective breeding, and hybrids.

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...
