Genes Get Shuffled When Chromosomes Exchange Pieces
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....

Chromosomes and Genetic Mapping
Students are introduced to mapping by crossover frequency. Genes travel as packaged trains on chromosomes. They use this experiment, genetic mapping assignment, that allow students to quickly complete the assignment and yet examine the...
Curated OER
Comparison of Human and Chimpanzee Chromosomes
Students actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.

Meiosis
In this meiosis worksheet, student complete the blanks describing the process of meiosis. Students draw a diagram of homologous chromosomes.
Curated OER
Chromosomes and Genetic Mapping
Pupils create models of chromosomes using clay, coins, beads, or marbles. They complete a worksheet regarding their crossover frequencies they created with their chromosomes and gene models. They read an essay on sex chromosomes and...

Sex Cells Have One Set of Chromosomes; Body Cells Have Two
What's the difference between body cells and sex cells? Learners explore the question and the process of meiosis using an interactive lesson. An animation describes the discovery of meiosis and describes its phases for a detailed and...
Curated OER
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...

Dragon Genetics ~ Independent Assortment and Genetic Linkage
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 teaches...
Curated OER
Chromosomes
For this chromosomes worksheet, students complete a crossword puzzle with 33 questions about genetic mutation in chromosomes. They identify traits associated with certain genes.
Curated OER
Homologous Shoes
Students examine the concept of homology by observing their shoes and those of their classmates. They summarize the observations of everyone's shoes relating it to chromosomes in cells. They share their observations with the class.
Curated OER
The Chromosome Connection
Students evaluate the degree of chromosome similarity and difference between humans and apes. Students infer about the relationship between a human and ape based on similarities found.

Happy Face Spider Propagation
Students research genetic adaptations. In this chromosome lesson plan, students investigate dominant and recessive genes using spiders indigenous to Hawaii. Students create Punnett squares to determine the probability of passing specific...
Curated OER
Born of Blood
Students define attributes of human chromosomes and match them to make a human karyotype. In this investigative instructional activity students demonstrate how traits are encoded in genes found on chromosomes.

How Mistakes in Cell Division Can Result in down Syndrome and Miscarriages
Some genetic conditions occur without being inherited. The distinction becomes the focus of the lesson. It details the process of cell division that results in trisomy on various chromosomes. A worksheet highlights the results including...
