Sex-Linked Inheritance
Sex-linked traits indicate a gene's location on a specific chromosome. Scholars learn about sex-linked traits and the specifics behind color blindness in the videos. Then they complete the online interactive to apply their knowledge...

Genetics PowerPoint
If mom is bald, will her babies be bald? Here is a practical presentation that can answer that question. Viewers can take notes on the difference between dominant and recessive genes, mutations, and heritability. A large portion of the...
Curated OER
Sex-Linked Genes
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...

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...
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...

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...

A Genome Is an Entire Set of Genes
Today researchers identify a gene suspected of causing a genetic disease in a matter of days rather than years, thanks to the Human Genome Project. Young scientists learn about the Human Genome Project and the scientists who designed the...

Test Your Knowledge of Sex Determination
Humans, fruit flies, and reptiles have their own rules where sex chromosomes are concerned. Scholars flip through a slide show offering an explanation of the chromosomes that determine the sex of different species. What is female in one...

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

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

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 - 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...

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...

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...

Bacteria and Viruses Have DNA Too
In the 1940s, scientists discovered bacteria conjugation, the process of DNA transfer or bacterial sex. The discovery proved that bacteria and viruses contain DNA and led to a Nobel prize. Interested individuals learn about the...

Mendelian and Non-Mendelian Heredity
Tenth graders discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers...

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....

Genetics & Pedigrees
Students examine genetic inheritance patterns and pedigrees. After discussing sex-linked genes, students use pedigrees to determine the genotypes of parents in the P1 generation. They complete worksheets and disuss the results.

Parental Genes
Eighth graders explore how different organisms pass their traits to their offspring. In this life science instructional activity, 8th graders differentiate recessive and dominant alleles. They predict the phenotype based on the genotype...
Curated OER
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,...

When Heredity Follows Different Rules
In this heredity learning exercise, students will create 3 Punnett squares to determine the genotype and phenotype of the offspring from specific breedings. Then students will answer 7 true or false questions based on chromosomes and...

Geneticist for a Day
Students discuss and compose a document discussing the transmission of the Huntington's gene- dominant or recessive, sex linked, etc. Additionally, they ought to consider Dr. Wexler's own odds for contracting the disease.

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...
