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...

The Clark Family Story: Tracing the Cause of Hemophilia
Ms. Strohfeldt did not omit anything when she designed this comprehensive lesson plan on DNA mutation and sex-linked traits. Begin with a pretest as an anticipatory set. Read a case history of the Clark family and the occurrence of...
Curated OER
The Human Genotype
Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

Dragon Genetics - Understanding Inheritance
Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...

Genetics Practice 4: Pedigrees
Four two-generation pedigrees are presented in this genetics worksheet. For each, five questions are asked: Is the trait autosomal recessive, autosomal dominant, x-linked recessive, x-linked dominant, or y-linked dominant? Whenever...

Thomas Hunt Morgan and the White-Eyed Mutant
Find any article about the genetic research of Thomas Hunt Morgan on the sex-linked eye color trait in Drosophila melanogaster. After having your class read the selection, they can answer these eight critical-thinking questions. This is...

Pipe Cleaner Babies
Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

genetics
Parts of the cell as well as genetic material begin this presentation. As the slides continue, there are explanations of the main terms used in genetics. The structure of genetic material, chromosomes, and replication are summarized....

AP: Chapter 15: The Chromosomal Basis of Inheritance
AP biology course-takers peer into the workings of inheritance with this worksheet. They examine the Chromosomal Theory of Inheritance, Morgan's fruit fly experimentation, and sex-linked genetic traits. Vocabulary definitions and...

Raven Chapter 13 Guided Notes: Patterns of Inheritance
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...

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...

Genetics Basics
In this basics of genetics worksheet, students 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...

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...

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...

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,...
Curated OER
Human Genetics
In this biology worksheet, 9th graders describe whether the father or mother is affected by a sex-linked disorder and why. Then they name two genetic disorders that are caused by a recessive allele on the X-chromosome. Students also name...
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...

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...

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 this...

Probability Exercise
Follow fruit fly genetics with this probability activity. Biology scholars analyze the alleles of Bugsy, Daisy, Dino, and Lulu, considering traits for antennae, wing type, and eye color. They solve Punnett squares to determine the...

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.

Chromosomes Carry Genes
Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

Dragon Genetics Lab-Principles of Mendelian Genetics
Students study genetic traits using popsicle sticks as chromosomes. In this biology lesson, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.

Human Genetic Disorder Probabilities
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.
