Punnett Square Fun
The topics in the previous video about dominant and recessive traits are continued here as Sal Khan explains incomplete dominance, the randomness of genotypes and phenotypes, and covers how to calculate probabilities using Punnett squares for one or multiple traits.
Pea Plant Punnett Square Worksheet
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 complete Punnett squares, identify genotype and phenotype, and calculate ratios.
Using the Internet to Do Punnett Squares
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 used in the lesson include a summary, a tutorial, and the interactive opportunity. Get your biology class into the computer lab for a different way of working on Punnett Squares!
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 determine the probability of an offspring having certain traits. To end the activity, they complete a problem to determine the correct combination of genes related to hairless dogs.
Dihybrid Cross Punnett Squares
In this dihybrid cross worksheet, students complete two punnett squares for the cross of two traits. They determine the genotypes, phenotypes and phenotypic ratios of the offspring.
Human Traits-Punnett Squares
In this human traits worksheet, students use Punnett squares to determine the probability of genotypes and phenotypes for offspring. They also answer conclusion questions by completing simple monohybrid crosses.
Punnett Square Popcorn
In this genetics worksheet, students use the Punnett Square to learn about dominance and codominance in inherited traits. This worksheet has 1 short answer question and 6 problems to solve.
Incomplete Dominant and Codominant Traits Worksheet
A two-page worksheet 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, this will take them to the next step. Assign it as homework or use it as an assessment after some time have been invested in these genetics concepts.
Dragon Genetics ~ Independent Assortment and Genetic Linkage
Imagine a pair of dragons that produce offspring and determine the percentage of the hatchlings have wings and large antlers. This fantastic activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches them how to use Punnett squares. The exercises also illustrate the law of independent assortment and linked genes. The handout is ten pages long and will take days to work through, but it will definitely keep learners engaged!
New! Finding Nemo Genetics: Incomplete Dominance
Consider the genetics of the coral in which Nemo and his father live. Marine geneticists practice using Punnett squares to determine phenotypes and genotypes in incomplete dominance crosses. After solving three problems about the offspring of the coral, students then solve four problems about the colored pearls produced by oysters. This attractive and engaging worksheet is an ideal homework assignment for your biology class.
Using the Internet: Punnett Squares
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 are inherited.
Dare to be Punnett Square
Eighth graders become familiar with Punnett squares, specifically purpose, application and interpretation. Key terms from previous lessons (included below) are reviewed/reinforced before data is applied to a Punnett square and interpreted.
Students review genotypes and phenotypes by taking a quiz. They calculate the probability of hail. After discussing and observing Mendel's Punnett Squares, students calculate probability problems and then use Punnett squares to solve the problems and identify the genotypes and phenotypes.
Fifth graders examine how traits are passed to their offspring using Punnett Squares. They demonstrate how a Punnett Square works by physically moving around boxes taped on the floor, representing the different traits of chicks and feather colors.
Dihybrid Punnett Squares
Students construct Punnett squares to illustrate specific genotypic and phenotypic genetic outcomes. Students calculate the probability of achieving specific genotypic and phenotypic genetic oucomes, using dihybrid Punnett squares.
Bikini Bottom Genetics
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 with one that has short eyeballs? The stories are fictitious, but the concepts are still sound. This activity, which comes with an answer key, will make solving Punnett Squares much less square!
Finding Nemo Worksheet on Genetics
Now that Nemo has been found, it's time to find his phenotype. Using basic genetics, middle or high schoolers determine how to break down traits in an engaging worksheet that allows kids to show what they know about Punnett squares, genotypes, and phenotypes. To modify this, your young geneticists could work with partners to complete the handout.
SpongeBob RoundPants? What's the Chance?
Dive down to Bikini Bottom for a fantastic lesson on heredity! High school scientists make phenotype predictions for various characters based on given dominant and recessive traits. Use the PowerPoint here to review this concept before splitting learners into small groups. They experiment with probability using a coin toss, organizing findings on a worksheet (linked). Next, they conduct a virtual lab to practice completing Punnett Squares and explore another interactive site with a quiz. Synthesize their skills with two Sponge Bob worksheets which, after completed by all groups, can be presented in a jigsaw fashion. Use the final quiz here as assessment.
Tracing a Genetic Disorder in a Family
In this genetic disorder worksheet, students understand how genetic diseases are passed down from parents to offspring. Students use Punnett squares to explain how a disorder is inherited. This worksheet has 10 short answer questions.
It's in the Genes!
