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...

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

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...

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

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...

In this biology worksheet, students answer 30 multiple choice trivia questions on various genetics and types of chromosome abnormalities.

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...

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.

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...

Students work as a class to first construct a pedigree of a popular singer, showcasing the singing gene being passed down through the generations. Students then make their own family pedigree and follow two traits through their family...

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...

Discuss an article about families affected by genetic disorders and their decisions about whether or not to evaluate their own genetic information. Investigate four different inherited disorders. Participate in a probability exercise....

In this Mendelian genetics worksheet, students answer a variety of questions about Mendel's experiments and discoveries and they practice determining probability of outcomes in pea plants.

In this biology worksheet, 9th graders identify and locate various vocabulary terms related to the study of genes. There are 18 biology terms located in the word search.

Students study genetic traits using popsicle sticks as chromosomes. In this biology lesson plan, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.

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,...

Students study the details of DNA restriction analysis and how RFLP's are used to locate genes on a map of DNA.

High schoolers 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...

Investigate the Hardy-Weinberg Principle to explain genetic equilibrium. The 10th lesson plan of a series of 12 is a laboratory exploration of genetic equilibrium. Your classes use a mixture of beans to model allele and genotype...

Seventh graders explore the connection between genetics and heredity by examining the cellular structure. Among the numerous activities to engage students are drawing DNA molecules, vocabulary puzzle sheets, and predicting possible...

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 resource will explore sex-linked genes which are a form of genetic linkage that depends on the X and Y sex chromosomes.

Thomas Hunt Morgan will explain the research he did to determine that some traits are linked to the sex of an individual.

An animated pedigree clearly explains the way hemophilia was inherited in the Romanov family. Interpreting pedigrees and sex-linked crosses should be much easier to understand after going through this tutorial.
