Students explore genetic terms, the Law of Dominance and the contributions of Gregor Mendel. After discussing Mendel's lab and his pea plants students observe examples of a phenotype chart. Afterward, they conduct their own lab to...

Students participate in a genetics activity in which they determine genotypes and phenotypes for given traits. They work with a partner and create babies based on their genotypes. Once traits for babies are determined, they write...

In this genetic worksheet, high schoolers 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.

In this heredity worksheet, students review how genes are involved in the inheritance of certain traits through generations. Students complete a Punnett square and review probability. This worksheet has 11 short answer and 11 fill in the...

In this meiosis worksheet, students review vocabulary words associated with genetics, fertilization, heredity, phenotype and genotype. This worksheet has 6 matching and 9 fill in the blank questions.

Sixth graders complete a human traits survey.  In this genetics lesson students read articles and fill out a worksheet on genotype and phenotypes. 

Students investigate their environment by growing plants in class.  In this botany lesson plan, students discuss the lifespan of plants and animals and how they must be cared for continuously over time.  Students grow a plant...

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. 

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

High schoolers explore the field of genetics. Through a graphing activity, students assess four common traits. They complete a Meiosis I and II charts which represent possible gametes for an individual. High schoolers discuss...

Students revie the Law of Independent Assortment and Law of Dominance. They practice Punnet squares and predicting genetic outcomes and identify factors that influence heredity.

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.

Genetic traits are described as homozygous or heterozygous based on allele similarity. Homozygosity and heterozygosity are explained in this resource. Includes a chart highlighting their differences and some examples that occur in humans.

Resource provides a discussion of Mendel's law of segregation with a focus on genotype, phenotype, alleles, heterozygous/homozygous, and 2 x 2 Punnett squares.

This lesson will explain that genotypes can be either homozygous or heterozygous. It is 2 of 4 in the series titled "Types of Traits."

This lesson will explain that genotypes can be either homozygous or heterozygous. It is 3 of 4 in the series titled "Types of Traits."

This lesson will explain that genotypes can be either homozygous or heterozygous. It is 4 of 4 in the series titled "Types of Traits."

[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.

Read about phenylketonuria and the tests used to diagnose it in those who might have inherited this recessive trait.

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.

[Free Registration/Login may be required to access all resource tools.] Natural selection acts on the phenotype (traits or characteristics) of an individual. On the other hand, natural selection does not act on the underlying genotype...

In this activity, students simulate a Punnett square of a cross between two heterozygous individuals and produce a histogram. They compare actual and expected results of genetic crosses.

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...
