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...

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...

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 learning exercise. Geared toward AP or college biology learners, they explore not only the basic vocabulary and concepts, but also the Law of...

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...

Sex-Linked Genes
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, they examine...

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...

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...

Beyond Mendel's Laws of Inheritance
This PowerPoint jumps right into the details of unusual traits and how they are coded. Â The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this...

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...

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,...

Mendelian Laws Apply to Human Beings
Why are so many inherited diseases more prevalent in populations of specified races? Scholars learn about pedigrees and genetics using a reading, an animation, primary sourced letters, a short video, a biography, a guided practice...

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...

Nasonia Genetics-A Jewel of a Wasp
Students investigate the inheritance pattern of eye color in Nasonia wasps. In this genetics and inheritance lesson plan, students read about the life cycle of Nasonia wasps and hypothesize about the possibilities of eye color inherited...

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...

When Heredity Follows Different Rules
In this heredity worksheet, learners 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...

Recovering the Romanovs
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...

Karyotypes and Inheritance of Chromosomes
Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model...

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...

The Molecular Biology of Mutations and Muscular Dystrophy
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...

Human Genetics
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...

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.
