In this genetics learning exercise, 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...

In this dihybrid cross worksheet, students are given four crosses to complete using punnett squares. They determine the genotypic and phenotypic ratios of the offspring.

Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

For this biology worksheet, 9th graders identify which seed color is dominant in the given chart and explain why it is. Then they create a Punnett square showing the alleles of the parent plants and first generation of offspring.

Young scholars describe and apply the Mendellian principles of genetics, focusing predominantly on dominant and recessive genes. They demonstrate how two parents contribute genes and how those genes appear in their offspring. They...

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...

In this genetics learning exercise, students use a diagram showing the genetic offspring of plants with different types of seeds to answer 4 short answer questions. Then students determine the traits of offspring of different crosses in...

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

Eighth graders explore how different organisms pass their traits to their offspring. In this life science instructional activity, 8th graders differentiate recessive and dominant alleles. They predict the phenotype based on the genotype...

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...

Seventh graders discuss their own genetic traits. Using computers, they research the creation of Punnett Squares. They preform online experiments with peas, predicting the appearances of the offspring. They determine how genetic traits...

In this heredity worksheet, students will use diagrams and informational paragraphs about traits, alleles, and genotypes to complete 3 short answer questions.

Ninth graders complete a monohybrid cross and a dihybrid cross. For this biology lesson, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.

Pupils analyze genetic characteristics in a given family tree through the F2 generation. Students apply prior knowledge from Gregor Mendel's study with pea plants and his Laws of Heredity to answer questions.

Sixth graders consider heredity. In this science lesson plan, 6th graders gain an understanding of certain physical traits are inherited from their parents through the genes.

There are many ways to learn about Gregor Mendel and his pea experiments. This interactive tutorial requires users to actually plant, grow, and cross different plants to observe their traits. Pedigrees are also used to help show dominant...

This interactive activity, adapted from the Dolan DNA Learning Center, illustrates how Gregor Mendel used purebred yellow and green peas to show that some genes are dominant and others are recessive.

This site explains genetic beliefs before and after Mendel, and also includes a section on Mendel himself and his experiments, entitled, "The Monk and his Peas".

Explore the genetics of plants discovered by Gregor Mendel in the nineteenth century. These interactives will walk users through the planting and growth of pea plants, possible combinations of plans to alter traits, predict the results...

This site, which is provided for by the University of Arizona, gives problems online that correspond to basic Mendelian genetics. Test your knowledge once you've read about Mendel and accessed the links to the various subjects covered in...

This resource explains Mendel's first law (Law of Segregation) in detail. Includes Mendel's original experiments with results and conclusions.

This personal site gives the seven characteristics that Mendel observed and a fairly large background to what Mendel saw and interpreted.

This set of seven activities will proved a thorough review of Mendel's work. The interactive experiments are easy to follow and drive home the concepts.

Mendel's second law and how he arrived at it through his experiments. Includes vocabulary and examples.
