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...

Three autosomal pedigrees are printed on this assignment. Biology scholars read them and determine the phenotypes for several individuals and find which ones inherit different genetic disorders. This fundamental skill can be reinforced...

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...

Looking for a quick, hands-on activity to teach young scientists about Punnett squares through monohybrid crosses? then check out this one.

In this biology learning exercise, students complete a crossword puzzle with 38 questions on genetics. They identify the different parts and functions of a flower.

Students solve a crime by matching a suspect's blood type to physical evidence collected at the crime scene. In this forensic science lesson, students identify the different blood types. They explain how blood tests work.

In this genetic learning exercise, 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.

Blood types and transfusions are explained in reading passages at the top of the worksheet. A chart of blood type compatibility is also provided. Biology students answer comprehension questions and then exercise critical-thinking skills...

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.

In this dihybrid cross worksheet, learners complete two punnett squares for the cross of two traits. They determine the genotypes, phenotypes and phenotypic ratios of the offspring.

For this science worksheet, students find the answers to various types of heredity problems. They use the sheet to set goals for completing the unit.

Students investigate how traits are passed from parents to offspring via meiosis and fertilization. They recognize that the combination of alleles forming a gamete is random.

In this biology worksheet, students use the information given on genetics, Sponge Bob and other characters to complete each of the questions on the sheet. They write the phenotype for each stated trait. Students also determine the...

Students flip a pair of coins to determine what genotype and what phenotype their child have for 29 given traits. They draw a picture of their kid based on their coin flip phenotypes.

Young scholars 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. Young scholars...

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,...

This is a worksheet regarding human genetics where students can poll the class regarding specific 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...

Students explore the concepts of phenotypes and genotypes.  In this genetics lesson students work together to pick a superhero and determine the traits of the offspring. 

Eighth graders become familiar with Punnett squares, specifically purpose, application and interpretation. Key terms from previous lessons (included below) are reviewed/reinforced before data is applied to a Punnett square and interpreted.

This site, which is provided for by the University of Arizona, gives problems online that correspond to basic Mendelian genetics. Test your knowledge once you've read about Mendel and accessed the links to the various subjects covered in...

[Free Registration/Login Required] This flipchart show students how to use a Punnett Square to introduce how homozygous and heterozygous genotypes are inherited and how they determine phenotypes.

This site from Palomar College provides a good background on exactly what Mendel did. Vocabulary links throughout make this a very good introduction article for genetics.

Activity Overview Use the SciTools App to simulate a Punnett square. Make predictions about genetic crosses. Learn about the following concepts; genes, alleles, dominant alleles, recessive alleles, homozygous individuals, heterozygous...
