Pre-Activity Worksheet: Natural Selection
Although the instructions include reading from a specific textbook, the tasks are appropriate for any unit dealing with how genotype frequency changes over time. Junior biologists define five vocabulary terms and then answer five...

AP: Chapter 14: Mendel and the Gene Idea
A survey of Mendelian genetics is presented through this handout. Biology prodigies answer questions about the Law of Segregation, phenotypic ratios, and dominance. They define genetics vocabulary terms and describe various genetic...
Curated OER
Genetics Worksheet
In 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...
Curated OER
Heredity
In this science worksheet, students find the answers to various types of heredity problems. They use the sheet to set goals for completing the unit.
Curated OER
Let's Get Square
Learners predict possible phenotypic and genotypic outcomes for avariety of common plant hybrids. They review and explain the characteristics of dominant and recessive traits and explore Mendelian genetics. Students plot the possible...
Curated OER
Happy Face Spider Propagation
Students research genetic adaptations. In this chromosome instructional activity, students investigate dominant and recessive genes using spiders indigenous to Hawaii. Students create Punnett squares to determine the probability of...
Curated OER
Cell Reproduction and Inheritance
Students determine their inherited characteristics from their parents. In this biology lesson, students study the life of Mendel using an interactive website. They differentiate dominant and recessive characteristics.
Curated OER
Genetically Inherited Traits
Young scholars explore heredity by examining how traits are passed from parent to offspring. Genetic terminology is examined and examples of inherited traits discussed. calculating genetic probability is also investigated in this lesson.
Curated OER
Modeling a Gene Pool
In this genetic worksheet, students examine how gene frequency changes in a population of organisms. After completing 5 pre-lab questions, they work in pairs to collect data and answer 5 additional post-lab questions.
Curated OER
It's All in the Genes
Twelfth graders investigate the inheritance of traits through several hands-on activities that illustrate the transmission of genetic characteristics. Students study advanced topics including multiple alleles, polygenic traits,...
Curated OER
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
Exploring Human Traits
Students explore human behavior by participating in a class science game. In this human characteristics lesson, students identify different human traits that are passed down by each generation and the purpose each of them have. Students...
Curated OER
Super Hero Genetics
Students explore the concepts of phenotypes and genotypes. In this genetics activity students work together to pick a superhero and determine the traits of the offspring.
Curated OER
Using Blood Tests to Identify Babies and Criminals
Students solve a crime by matching a suspect's blood type to physical evidence collected at the crime scene. For this forensic science lesson, students identify the different blood types. They explain how blood tests work.
Curated OER
Punnett Squares
Pupils revie the Law of Independent Assortment and Law of Dominance. They practice Punnet squares and predicting genetic outcomes and identify factors that influence heredity.
