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...

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 worksheet covers the differences in genotypes and...

It's alive! Turn young biologists into mad scientists with this engaging genetics activity. Using their knowledge of chromosomes and genes, high schoolers create dragons with unique sets of traits,...

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...

Students use mutant corn ears to investigate inheritance patterns. In this inheritance lesson plan, students count the number of corn kernels of each phenotype in mutant and wild type ears of corn. Students calculate the ratio of...

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...

Students review genetic concept of traits, define and discuss phenotypes and genotypes, examine differences between single gene traits and multiple gene traits, and compare and record phenotypes with every other student in class.

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

Students are introduced to the cellular machinery assorts the pairs of chromosomes randomly and independently during meiosis. They are introduced to the rich genetic variation occurs as a result of the random and independent assortment...
