Linked Genes Teacher Resources

Scholars analyze Morgan's fruit fly lab to learn how genes are linked. The instructor shows that the data from a dihybrid cross was not what Morgan expected, and when re-crossed numerous times, the data did not change. Viewers see gene...

Are your biologists ready for advanced genetics? Briefly learn about Gregor Mendel, and dive into the phylogenetic tree, linked genes, multiple genes and nonnuclear inheritance! Mr. Anderson continues his clear instruction and use of...

High schoolers 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 plan, they...

Imagine a pair of dragons that produce offspring. What percentage of the hatchlings have wings and large antlers? An engaging activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and...

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...

The strengths and problems associated with Mendelian genetics are explored in a video that first reviews Mendelian genetics and independent assortment. Viewers then explore problems with Mendelian genetics such as linked genes,...

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...

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.

Young scholars 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.

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...

Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....

The instructor in a biology video defines and shows examples of incomplete dominance, codominance, epistasis, and multiple alleles. Viewers then explore Thomas Hunt Morgan and his crosses showing the discovery of gene linkage via fruit...

Genetics hopefuls solve Punnett Squares for monohybrid and dihybrid crosses. An example of each is provided to teach the process. Other heredity patterns are mentioned and genetic disorders are listed in the second half of the...

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 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...

Students explore the gene frequency in Hardy-Weinberg Equilibrium experiments. They inquire into the studies of both black and gray squirrels. Basically the population genetics of certain squirrel populations. The species of each are...

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

Use these flashcards to review topics in cell reproduction, recombination, linkage, and sex-linked genes.

[Free Registration/Login may be required to access all resource tools.] While studying genetics, students will investigate sex-linked genes and what inherited diseases are associated with the genes. Students will also explore pedigree...

This site, provided by The University of Arizona, gives a good set of genetics problems that involve sex-linked genes. Great to review what you know! Links are provided to access the various subjects covered in this problem set.

[Free Registration/Login may be required to access all resource tools.] Discusses linked genes and why some characteristics are inherited together.

[Free Registration/Login may be required to access all resource tools.] Discusses linked genes and why some characteristics are inherited together.

Paul Andersen explains aspects of genetics that were not covered by Gregor Mendel. He begins with the following topics; incomplete dominance, codominance, epistasis, multiple alleles, and multiple genes. He then explains how linked genes...

Learn about the difference between the X and Y chromosome in this Khan Academy video. Video discusses sex-linked genes that cause color blindness and hemophilia on the X chromosome. [14:18]
