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,...

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...

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...

Four two-generation pedigrees are presented in this genetics worksheet. For each, five questions are asked: Is the trait autosomal recessive, autosomal dominant, x-linked recessive, x-linked dominant, or y-linked dominant? Whenever...

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 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...

Harness young scientists' knowledge of genetics with an engaging science activity. Students start by flipping a coin to determine the genotypes and phenotypes of two parent monsters, before using Punnett squares to...

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...

Three autosomal pedigrees are printed on this assignment. Biology scholars read them and determine the phenotypes for several individuals and find which ones inherit different genetic disorders. This fundamental skill can be reinforced...

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

In this basics of genetics instructional activity, 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,...

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...

In this genetics worksheet, 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...

In this genetics problems worksheet, students solve 20 problems by completing crosses using Punnett squares in order to predict the probability of genotypes and phenotypes of offspring.

In this biology instructional activity, students use the information given on genetics, Sponge Bob and other characters to complete each of the questions on the sheet. They write the phenotype for each stated trait. Students also...

Biology aces answer four questions about genetic recombination and nine questions about pedigrees. This worksheet is very focused on these two topics. Most of the pedigree questions relate to the genetic disorders, Alkaptonuria and...

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

Finally, here is a genetics learning exercise 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...

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...

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...

Given the phenotypes of offspring in mice, flowers, and human blood type, genetics pupils practice determining the genotypes of the parents. Four short answer questions follow. The entire assignment will require learners to put on their...

In this biology activity, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...

In this genetics activity, students use descriptive information about the different types of Oompa Loompas to show genotype and phenotype plus dominant and recessive traits. This activity has 12 problems to solve.

In this biology worksheet, students complete a crossword puzzle with 38 questions on genetics. They identify the different parts and functions of a flower.
