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,...

How often do you find a science learning exercise that comes with separate teacher's instructions? Here is one of those rare instances. Goals and objectives, materials, and evaluation guidelines precede the actual assignment. Biology...

Finally, here is a genetics worksheet 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...

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...

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...

A series of math and science activities feature M&M's® as manipulatives to help kids work through equations. The resource includes exercises on finding averages, percent of compositions, moles in chemical reactions, genotypes and...

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...

In this meiosis worksheet, students review vocabulary words associated with genetics, fertilization, heredity, phenotype and genotype. This worksheet has 6 matching and 9 fill in the blank questions.

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.

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...

Looking for a quick, hands-on activity to teach young scientists about Punnett squares through monohybrid crosses? then check out this one.

Geneticists of the future identify heterozygous and homozygous genotypes, describe phenotypes, and use Punnett squares to solve problems and determine characteristics of offspring. A total of 15 questions make this a compact quiz or...

In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

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 learning exercise covers the differences in genotypes...

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...

Matching and fill-in-the-blank exercises give biology whizzes a chance to practice vocabulary associated with evolution. Terms to be reviewed focus on evidence for evolution, natural selection concepts, and some genetics words. You could...

What do you get when you cross a purple with a white? Genetics geniuses figure it out with a Punnett square. On this assignment, they must solve crosses for incomplete dominance, codominance, lethal dominance, and sex-linked genes. It is...

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...

Practice calculating genetic probability, listing gametes, and identifying genotypes. The worksheet combines short answer questions with practice problems to solve. It would make a revealing review assignment or even a practical pop quiz...

In this short space, it would be impossible to describe the breadth of this seven-page genetics worksheet. Geared toward AP or college biology learners, they explore not only the basic vocabulary and concepts, but also the Law of...

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...

Freddy's Friendly Fruit Market is under attack by fruit flies, and it is up to your aspiring biologists to solve the crime! By reading and analyzing the phenotypes, detectives determine which fly is responsible. This memorable assignment...

For 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.

In this genetics worksheet, students fill in the blanks with terms related to genes, alleles, genotypes, phenotypes and heredity. They use their answers to complete a joke.
