Genetics in Harry Potter’s World Lesson 2
Can we find the phenotypes and genotypes of magical ability for the characters in Harry Potter? Of course, but first we need to understand incomplete or blended dominance, co-dominance, multiple alleles, and regulatory genes. This...

Genetics Practice 1: Basic Mendelian Genetics
Six genetics problems are to be solved by junior geneticists. Empty Punnett squares are provided for them to plant the parents' alleles and determine the genotype, phenotype, and frequency of offspring. All of the problems involve actual...

AP: Chapter 23: The Evolution of Populations
How and why do populations change over time? AP biology aces explore this question by completing this assignment. They write the answers to 21 questions regarding population genetics, stability, genetic drift, polymorphism, and...

Genetics and The Work of Mendel
If you need a summary of all aspects of Mendelian genetics then this slideshow is for you. The information included is essential for complete understanding of crosses, genotypes, phenotypes, and heredity.

In Sickness and in Health
Based on family history, how likely is it that a couple's children will have a recessive disease? In an in-depth, but easy-to-follow case study, future geneticists learn the story of Greg and Olga, who are hoping to have children, but...

Measuring Evolution of Populations
The Hardy-Weinberg principle is the focus of this concise slideshow. Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W...

Genetics
Students explain the difference between dominant and recessive genes, identify what causes differences in the traits of parents and their offspring, and explain how sex is determined. They will also improve their reading and...

What Do Genes Look Like?
Seventh graders describe the basic structure of the DNA molecule. They identify what an inherited trait is and how it can be determined by one or more genes. Finally, 7th graders identify that plant and animal cells contain several...

Heredity: Your Connection To The Past
Young scholars investigate genetics and the process of reproduction in living organisms.
Curated OER
Genetics
Students create a checklist of traits common in all of their families. Uisng a table, they compare and contrast their family members to non-family members. They also review dominant and recessive traits and discuss how knowing about...

When Heredity Follows Different Rules
In this heredity worksheet, students will create 3 Punnett squares to determine the genotype and phenotype of the offspring from specific breedings. Then students will answer 7 true or false questions based on chromosomes and sex-linked...

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.

Activity: Gummy Bear Genetics
Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity worksheet covers the differences in genotypes and...

How to Conquer a Genetic Disease
Students study the details of DNA restriction analysis and how RFLP's are used to locate genes on a map of DNA.

DNA Detectives
Fifth graders define dominant and recessive genes and that they have DNA from their mother and father. In this inherited traits lesson, 5th graders complete a punnet square based on their parents traits. Students decorate...

Hardy-Weinberg Equilibrium
Students investigate how Hardy-Weinberg Equilibrium is established and what assumptions and conditions are necessary to reach Equilibrium. They model alleles using materials such as index cards, M & M's and goldfish.
Curated OER
Patterns of Heredity
Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

How You Become a Unique Individual
Students investigate how traits are passed from parents to offspring via meiosis and fertilization. They recognize that the combination of alleles forming a gamete is random.

Designer Babies
Students differentiate phenotypes and genotypes. In this genetics lesson, students complete the punnett square. They design their own baby by choosing the phenotype they want.

Genetics Mendelian
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...

Genetics - The Study of Inheritance
In this genetics worksheet, students will compare four pea plants with different alleles that control flower color and complete 5 short answer questions. Then students will read 8 statements about genetic mutations and determine if the...

If Your Mom Has Big Feet, Will You Have Them Too?
Pupils describe and apply the Mendellian principles of genetics, focusing predominantly on dominant and recessive genes. They demonstrate how two parents contribute genes and how those genes appear in their offspring. They describe...
