Does where we live influence how our bodies express genetic traits? Explore variation in human skin color with an activity that incorporate video and hands-on learning. Individuals model the relationship between phenotypes and genotypes,...

The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

Genetic analysis has gone to the dogs! Learners use real DNA information collected from dog saliva to study the relationship between genotypes and phenotypes. They analyze alleles to determine correlations to coat color, length, and...

Freddy's Friendly Fruit Market is under attack by fruit flies, and it is up to your aspiring biologists to solve the crime! By reading and analyzing the phenotypes, detectives determine which fly is responsible. This memorable assignment...

In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Students learn the difference between a genotype and a phenotype. They demonstrate that recombination of gametes (coins) will result in the formation of unique individuals.

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 biology activity, students use the information given to complete each of the questions. They indicate whether each genotype is heterozygous or homozygous. Students also complete the Punnett square to illustrate the possibilities...

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

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. 

Students create a family pedigree, relate the laws of inheritance to a family pedigree, and determine certain phenotypes and corresponding genotypes of members in their family.

In this biology learning exercise, 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...

In this genetic worksheet, 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 situations.

In this heredity worksheet, students will use diagrams and informational paragraphs about traits, alleles, and genotypes to complete 3 short answer questions.

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...

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...

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.

Eighth graders interpret the genotypes and phenotypes, then pair up chromosomes.

In this biology worksheet, 9th graders determine whether it is possible for two alleles to produce four genotypes. Then they state how many alleles there are for blood type. Students also determine which blood type is inherited by...

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...

Students review genetic concept of traits, define and discuss phenotypes and genotypes, examine differences between single gene traits and multiple gene traits, and compare and record phenotypes with every other student in class.

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

Discover possible genetic outcomes through Punnett Squares. Learners continue studying genetic traits in the 10th lesson in the 17-part series. After determining the father of Sparky's kittens, scholars now attempt to predict the traits...

Young scholars use a rapid method to render the bacterium Escherichia coli "competent" in order to uptake plasmid DNA. They also have growth on the plain LB plates by the untransformed cells (which serve as controls). Students perform a...
