Sex-linked Inheritance Teacher Resources

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...

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...

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 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...

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...

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...

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...

For 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...

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,...

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

In this heredity activity, 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 sex-linked...

Students use DNA to solve an identity mystery. In this biology lesson, students use the Internet to gather information about sex-linked disorders and complete a Punnett square for hemophilia, then examine a handwriting analysis, ear...

In this basics of genetics activity, learners 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...

In this biology learning exercise, 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...

In this biology worksheet, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the daughter is...

Learners 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.

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.

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.

Young scholars develop a working vocabulary of terms related to the life cycle. In small groups, students play the life cycle's game which consists of matching and defining vocabulary. Directions for creating the game board are...

In this chromosomes instructional activity, students complete a crossword puzzle with 33 questions about genetic mutation in chromosomes. They identify traits associated with certain genes.

Learners cross wild type flies and mutants, both purchased from a biological supply house (Carolina Biological Supply or Wards, for example) in groups from lesson one.

Students idenitfy that cancer is a growth of mutated cells and that cancer cells are only one type of cell that causes disease in our body. They also identify that all eukaryotic cells contain a nucleus, cytoskeleton, and a cell...

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...

[Free Registration/Login may be required to access all resource tools.] What determines if a baby is a male or female? Recall that you have 23 pairs of chromosomes-and one of those pairs is the sex chromosomes. Everyone has two sex...
