Genetics Practice: Beyond the Basics
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...

Should States Repeal Their Laws Banning First Cousin Marriage?
Around half of the states in the US ban first cousin marriage, but does science support that ban? Scholars work through genetic analysis of the risks to understand if more states should ban the practice—or if some should remove it. They...

Sex-Linked Genes and Disorders
In this genes worksheet, students determine how the gender of a baby is produced plus explore sex-linked disorders such as hemophilia. This worksheet has 20 fill in the blank and 8 short answer questions.

Genetic Inheritance Follows Rules
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...
Curated OER
Genetics Worksheet
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...

Color Vision Genetics Evolution Simulation
At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

In Sickness and in Health
Based on family history, how likely is it that a couple's children will have a recessive disease? In an in-depth, but easy-to-follow case study, future geneticists learn the story of Greg and Olga, who are hoping to have children, but...
Curated OER
Human Inheritance
Students analyze genetic characteristics in a given family tree through the F2 generation. Students apply prior knowledge from Gregor Mendel's study with pea plants and his Laws of Heredity to answer questions.

University of Arizona: Sex Linked Inheritance
This site from the University of Arizona provides great information on a sex-linked inheritance problem set. This is a very good site to practice what you know about sex-linked problems. Each link is a problem.

The Biology Project: Human Biology: Color Blindness Problem Set
This problem set is based on a question received from a woman with red-green color blind as well as other members of her family. She wanted to know if we could help her understand how she inherited her color blindness.

Pbs: Our Genes/our Choices: The Probabilities of Problems: A Look at Inheritance
Learn how the genes inherited from two parents can be recombined in their offspring in this simulation activity. In addition, investigate the probabilities of passing on inherited genetic disorders.
