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,...

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...

What a fun way to explore Mendelian Genetics! Using a computer connected to the Internet, beginning biologists construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Other websites...

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...

Hilarious! Use the characters from SpongeBob Square Pants to practice solving genetics problems! Yellow sponge body color is dominant to blue. Square body shape is dominant to round body shape. Did someone switch Mr. Krab's baby...

How often do you find a science worksheet 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 leaners...

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...

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...

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...

Although the instructions include reading from a specific textbook, the tasks are appropriate for any unit dealing with how genotype frequency changes over time. Junior biologists define five vocabulary terms and then answer five...

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.

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...

In this genetics worksheet, students complete 8 problems where they fill out Punnett squares and find the percentage of genotypes and phenotypes. This fine worksheet could be used for in-class independent practice, or as a homework...

Students determine which adaptations allow an organism to survive and reproduce in a certain environment. Students act as "predators" to pick up acetate discs "prey" scattered around the classroom. Students list the number found, the...

In this genetic worksheet, high schoolers will complete 4 fill in the blank questions about selective breeding and determining genotypes. Then students will use a Punnett square to determine the genotype for two different breeding...

Learners participate in a genetics activity in which they determine genotypes and phenotypes for given traits. They work with a partner and create babies based on their genotypes. Once traits for babies are determined, they write...

Pupils study the basics of genetics and the father of genetics Gregor Mendel.

This site from Palomar College provides a good background on exactly what Mendel did. Vocabulary links throughout make this a very good introduction article for genetics.

A detailed website that explains the history and process of classifying animals using evolutionary, molecular, and physical characteristics relationships. Website also contains information on evolution and evolutionary processes....

[Free Registration/Login may be required to access all resource tools.] Describes genotype and phenotype, and how genes are inherited.

Take this interactive quiz over Mendelian and molecular genetics, then review your score and any missed questions at the end.

Cross different types of peas and study the phenotype and the genotype of the offspring.
