Curated OER
Genetics and the Work of Mendel
Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images...
Curated OER
Fruit Fly Ranch Activity
Seventh graders describe how the traits of an organism are passed from generation to generation. They distinguish between asexual and sexul reproduction. Students identify traits through genes and those resulting from interactions with...
Curated OER
Zork Genetics
For this genetics worksheet, students use an imaginary species and a list of genetic traits and the alleles that code for each trait to determine the genotype and phenotype probabilities of offspring. Students complete nine monohybrid...
Curated OER
Heredity Worksheet #3
In this heredity worksheet, students complete two monohybrid crosses and predict the expected outcome of genotypes and phenotypes. They answer five questions about each genetic cross.
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
Human Genetic Disorder Probabilities
In this genetic disorders worksheet, learners complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.
Curated OER
Pea Plants Dihybrid Cross
For this dihybrid cross worksheet, students are given four crosses to complete using punnett squares. They determine the genotypic and phenotypic ratios of the offspring.
Curated OER
Dihybrid Cross Punnett Squares
In this dihybrid cross worksheet, students complete two punnett squares for the cross of two traits. They determine the genotypes, phenotypes and phenotypic ratios of the offspring.
Curated OER
Punnett Squares
Eighth graders take a short quiz on genotypes and phenotypes. As a class, they are introduced to the concept of Punnett Squares and listen to a description of Gregor Mendel's pea experiment. In groups, they complete Punnett Squares to...
Curated OER
The Blue Genes Challenge
Students practice completing and analyzing Punnett squares. They create Punnet squares in response to a provided scenario from the company Blue Genes Incorporated. In addition, they complete an activity to determine the phenotype of...
Curated OER
Teacher Preparation Notes on Genetics
Students explore genetics through various hands-on activities. For this biology lesson, students predict the probability of offspring genotypes and phenotypes using the Punnett Square. They explain the causes of genetic abnormalities.
Curated OER
A Sputtering Image
Students explain the role of genes in heredity. In this biology lesson, students predict the offspring's genotypes and phenotypes using the Punnett Square. They compute the probability of genotypes and phenotypes.
Curated OER
Plastic Egg Genetics
Pupils are introduced to the concepts of genetic dominance, recessiveness, related terms, Punnett Squares, etc.
Curated OER
Dare to be Punnett Square
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.
Curated OER
Probability and Genetics
Students determine the offspring from a genetic cross. In this biology instructional activity, students use Punnett squares to find probability. They explain how genes are passed from parents to offspring.
Curated OER
Punnett Squares
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.
Curated OER
Genetics: Punnett Squares
Students examine Punnett squares charts and analyze how they are used for successful breeding and predictions of certain traits. They complete interactive Punnett square charts, quizzes, problems, and concentration games.
