Problem Solving In Genetic Disorders
Students explore the causes and effects of genetic disorders. They examine the phenotype and genotype of individuals and predict the recurrenence risks. Students generate a Punnett square and construct pedigree charts.

Human Genetic Disorder Probabilities
In this genetic disorders worksheet, high schoolers complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.

Pea Plants Dihybrid Cross
In this dihybrid cross worksheet, students are given four crosses to complete using punnett squares. They determine the genotypic and phenotypic ratios of the offspring.

"Easter" Egg Genetics
Using plastic Easter eggs to represent parent phenotypes, genetics enthusiasts simulate the passing of alleles. They record the phenotype of each half of the egg, one representing the mother's and one representing the father's. They...

Teacher Preparation Notes on Genetics
Students explore genetics through various hands-on activities. In this biology lesson plan, students predict the probability of offspring genotypes and phenotypes using the Punnett Square. They explain the causes of genetic abnormalities.
Curated OER
What is Genetics?
In this biology activity, 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...

Unit 3: Genetic Variation
What happens when genes change? Junior genetic investigators examine the effects of mutation in the third unit of a four-part Biotechnology series. Individuals discover the types of mutations through a series of PowerPoints, then partner...

Heredity Worksheet #3
In this heredity worksheet, learners complete two monohybrid crosses and predict the expected outcome of genotypes and phenotypes. They answer five questions about each genetic cross.
Agriculture in the Classroom
Roll of the Genes
Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...

Punnett Squares/Genetics
Ninth graders complete a monohybrid cross and a dihybrid cross. In this biology lesson, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.

Biology: Genetics and Heredity
Seventh graders explore the connection between genetics and heredity by examining the cellular structure. Among the numerous activities to engage students are drawing DNA molecules, vocabulary puzzle sheets, and predicting possible...

Probability and Genetics
Learners determine the offspring from a genetic cross. In this biology lesson, students use Punnett squares to find probability. They explain how genes are passed from parents to offspring.
