Natural Selection of Strawfish
A sequence of pictures accompany a few statements that help define the differences between phenotype and genotype. The slides must be used to accompany a lecture as they do not really explain any concepts. The 5th slide is the most...

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
Punnett Practice
In this genetics learning exercise, students complete 8 problems where they fill out Punnett squares and find the percentage of genotypes and phenotypes. This fine learning exercise could be used for in-class independent practice, or as...

Sixth graders complete a human traits survey. In this genetics lesson students read articles and fill out a worksheet on genotype and phenotypes.
Curated OER
The Acetate Animal Hunt
High schoolers determine which adaptations allow an organism to survive and reproduce in a certain environment. Students act as "predators" to pick up acetate discs "prey" scattered around the classroom. High schoolers list the number...

Heredity Worksheet: Blood Type
In this genetics worksheet, students use Punnett squares to determine the possible genotypes of offspring based on blood type. This worksheet has 6 problems to solve.
Curated OER
The Structure of DNA
In this the structure of DNA worksheet, students read a passage about the structure of DNA in bacteria and then relate that information to answer the questions given.

Genetic Technology
In this genetic learning exercise, students will complete 4 fill in the blank questions about selective breeding and determining genotypes. Then students will use a Punnett square to determine the genotype for two different breeding...
Curated OER
Human Heredity II
Using deductive skills and reasoning based on the data provided about a family's blood genotype, blood phenotype, chromosomes, and genetic conditions, 9th graders answer the questions below. The conditions discussed are Down Syndrome and...
Curated OER
What is Genetics?
In this biology worksheet, 9th graders identify which seed color is dominant in the given chart and explain why it is. Then they create a Punnett square showing the alleles of the parent plants and first generation of offspring.
Curated OER
Genetics Since Mendel
In this biology worksheet, 9th graders describe how two alleles can produce three phenotypes. Then they create a Punnett square showing the possible offspring of red and white cattle. Students also determine the genotypes and phenotype...
Curated OER
Human Genetics
For this biology worksheet, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the daughter is...
Curated OER
What is Genetics?
In this biology worksheet, 9th graders name two forms of the trait for seed shape observed by Mendel. Then they determine the percentage of the possible types of offspring that have the same genotype as the parents. Students also explain...
