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,...

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

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...

In this genetics practice worksheet, students answer fifteen questions about homozygous and heterozygous genotypes and simple monohybrid crosses of traits. They determine genotype and phenotype ratios by completing Punnett squares for...

Have you ever wondered why you aren't taller or invisible? It all comes down to your dominant and recessive genes. Introduce your class members to genetics with a presentation that includes worksheets for young geneticists to...

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...

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

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 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...

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...

Around half of the states in the US ban first cousin marriage, but does science support that ban? Scholars work through genetic analysis of the risks to understand if more states should ban the practice—or if some should remove it. They...

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...

The main objective of this activity is to illustrate the variation that results from crossing-over during prophase I of meiosis. Other sources of variation from generation to generation are: (1) independent assortment (223 possible...

Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model...

In this genetics instructional activity, students complete 3 dihybrid crosses of traits to determine the probability of the genotypes and phenotypes of the offspring of the imaginary species, the Zork.

In this worksheet, students will answer 4 fill in the blank statements about Mendelian inheritance and meiosis. Then students will use Punnett squares to answer three short answer questions. Students will match 8 genetics vocabulary...

In this biology 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 determine the...

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

In this genetics worksheet, high schoolers use a Punnett square to determine the genotypes and phenotypes of the offspring of a dihybrid cross. Then students complete 10 fill in the blank questions.

In this heredity instructional activity, 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...

In this basics of genetics 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, answer five...

In this heredity activity, students complete two monohybrid crosses and predict the expected outcome of genotypes and phenotypes. They answer five questions about each genetic cross.

In this genetics learning exercise, students are given two coins that they mark with a "F" and a "M" to represent parents. They flip the coins to determine the genotype and phenotype of the offspring for twelve traits. They also use the...

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...
