Beyond Mendel's Laws of Inheritance
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...

Genetics of Parenthood
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,...

Zebrafish and Skin Color
You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...
Curated OER
Patterns of Heredity
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...
Curated OER
Karyotypes and Inheritance of Chromosomes
Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model...

AP: Chapter 14: Mendel and the Gene Idea
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...

Understanding Variation
Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

Genetics Since Mendel
In this biology worksheet, 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 by...

Soap Opera Genetics – Genetics to Resolve Family Arguments
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...
Curated OER
Mendellian Genetics
Young scholars describe the inheritance patterns other than simple dominance. They are taught how Mendel's principles apply to all organisms. Students review the use of Punnett Squares. They are taught the principles of probability...
Curated OER
It's All in the Genes
Twelfth graders investigate the inheritance of traits through several hands-on activities that illustrate the transmission of genetic characteristics. Students study advanced topics including multiple alleles, polygenic traits,...
Curated OER
The Genetics of Parenthood
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...
Curated OER
Human Heredity II
Using deductive skills and reasoning based on the data provided about a family's blood genotype, blood phenotype, chromosomes, and genetic conditions, 9th graders answer the questions below. The conditions discussed are Down Syndrome and...
