How Can You Predict the Characteristics of an Unborn Baby?
Students compare three sets of unlabeled human chromosomes and gather related data, trace chromosomes to pair them, and make observations about them.
Curated OER
Patterns of Heredity
Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

Modeling Allele Distribution Through Meiosis and Fertilization
The main objective of this activity is to illustrate the variation that results from crossing-over during prophase I of meiosis. Other sources of variation from generation to generation are: (1) independent assortment (223 possible...
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.
Curated OER
Don't Delete Me
Fourth graders explore genetic disorders, which can be caused by a malfunction in a particular chromosome and how these can cause genetic mutation.
Curated OER
The Genetic Counseling Game
Pupils explore genetics and ethical issues. They siimulate the role of genetic counselors, perform fictitious tests, and gather information about parents and fetuses in case studies. Students describe the condition and formulate a...

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.
Curated OER
Genes
Students discuss the difference between a gene, DNA, chromatid, and chromosome. They predict how changes in chromosome number or structure affect development. Students discuss what causes genetic disorders. They view a PowerPoint that...
