Incomplete Dominant and Codominant Traits Worksheet
A two-page instructional activity provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares,...

Dragon Genetics ~ Independent Assortment and Genetic Linkage
Imagine a pair of dragons that produce offspring. What percentage of the hatchlings have wings and large antlers? An engaging activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches...
Curated OER
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...
Curated OER
Genes within Populations
Finally, here is a genetics activity that does not include Punnett squares! Designed for a more advanced class, biology learners will compare Lamarck's concept of evolution with Darwin's. They will explore the Hardy-Weinberg equilibrium...
Curated OER
"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...
Curated OER
Probability Exercise
Follow fruit fly genetics with this probability activity. Biology scholars analyze the alleles of Bugsy, Daisy, Dino, and Lulu, considering traits for antennae, wing type, and eye color. They solve Punnett squares to determine the...
Serendip
Genetics
A handout on genetic inheritance begins with a reading on alleles and how they can result in albinism. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn...

Genetics Practice 4: Pedigrees
Four two-generation pedigrees are presented in this genetics learning exercise. For each, five questions are asked: Is the trait autosomal recessive, autosomal dominant, x-linked recessive, x-linked dominant, or y-linked dominant?...

7.012 Genetics Section Problems
A set of phenotypes is listed for mice, flowers, blood type, and plants. For each, biology buffs analyze the percentages of phenotypes in the offspring and then identify the genotypes of the parents. This is a different approach to...

Mendelian Genetics
How did Mendel know which pea plants would demonstrate certain characteristics? Pupils explore the answer this question, among others, as they complete Punnet squares, research dominant and recessive traits, and explore hereditary...

AP: Chapter 14: Mendel and the Gene Idea
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...

Heredity: Traits, Genes, Alleles
If you knew people would pay extra for a bald dragon, could you pick which parents you should breed in order to get the highest number? The unit examines heredity and genetics through breeding dragons, mice, dogs, and tries to figure...
Curated OER
Genetics Challenge
In this genetics worksheet, high schoolers fill in the blanks with terms related to genes, alleles, genotypes, phenotypes and heredity. They use their answers to complete a joke.
Curated OER
Using the Internet to Do Punnett Squares
What a fun way to explore Mendelian Genetics! Using a computer connected to the Internet, beginning biologists construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Other websites...

Dragon Genetics - Understanding Inheritance
Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...

Were the babies switched? – The Genetics of Blood Types
Human biology or genetics learners apply their knowledge to a unique situation: two newborn baby girls being possibly switched in the hospital. The engaging activity ends with a Punnett squares assignment in which pupils evaluate whether...

Exploring Genetics Across the Middle School Science and Math Curricula
Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...
Curated OER
Genetics Basics
For this basics of genetics worksheet, students review the concepts of genetic inheritance by writing the alleles for genetic traits inherited in offspring. They identify dominant and recessive traits given allele pairs, answer five...
Curated OER
Mendelian and Non-Mendelian Heredity
Tenth graders discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers...
Curated OER
Zork Genetics
In this genetics activity, 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...

The Wonders of Horse Coat Color
You won't be able to use a few of the slides in this presentation since the first lists objectives not met within, and the third gives instructions to a worksheet that is not included. You will, however, find the remaining slides useful...

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...
