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,...

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...

TE Lesson: What's Dominant?
Students study the number of chromosomes in the body cells, sperm cells, and egg cells of humans. They define allele, and examine the difference between dominant and recessive alleles. They complete an activity with jelly beans that...

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...

Hairy Heredity
Young scholars learn that heredity comes down to the flip of a coin with this cross-curricular math and science lesson. Using smiley faces as a model, students toss coins to determine which dominant or recessive traits will be passed on...

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...

Genetics in Harry Potter’s World Lesson 1
By the end of Harry Potter and the Deathly Hallows, we know Harry and Ginny get married, but what will their kids look like? This presentation introduces viewers to Punnett Squares and how to use them to determine both dominant and...

Heredity Worksheet #1
In this genetics learning exercise, students review the experiments on pea plants that Mendel used to explain dominant and recessive alleles. This learning exercise has 10 fill in the blank questions.

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...

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...

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...

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...

"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...

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...

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?...
