Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

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...

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...

Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images...

Two individuals share 99.9 percent of their genetic codes, yet diversity is observed everywhere. Young scientists learn about diversity through hands-on activities and an experiment. They apply the concepts of independent assortment and...

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...

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...

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 learning exercise, students 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.

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...

If you need a summary of all aspects of Mendelian genetics then this  slideshow is for you. The information included is essential for complete understanding of crosses, genotypes, phenotypes, and heredity.

Don't want to sound corny, but your class will be a-maize-d by an engaging activity! Explore the history of the modern corn plant through a video and Punnett squares. Junior genetics experts get hands-on experience with actual research...

Genetic analysis has gone to the dogs! Learners use real DNA information collected from dog saliva to study the relationship between genotypes and phenotypes. They analyze alleles to determine correlations to coat color, length, and...

Eighth graders take a short quiz on genotypes and phenotypes. As a class, they are introduced to the concept of Punnett Squares and listen to a description of Gregor Mendel's pea experiment. In groups, they complete Punnett Squares to...

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 a world of DNA testing popularity, understanding how to solve basic genetic problems allows scholars to better understand and interpret test results. They work through many different types of genetic problems using statistics, Punnett...

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...

In this biology learning exercise, 9th graders describe how two alleles can produce three phenotypes. Then they create a Punnett square showing the possible offspring of red and white cattle. Students also determine the genotypes and...

In this heredity worksheet, 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 and sex-linked...

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