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.
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!
How often do you find a science activity 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.
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 instructional activity, they complete a problem to determine the correct combination of genes related to hairless dogs.
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.
In this human traits activity, students use Punnett squares to determine the probability of genotypes and phenotypes for offspring. They also answer conclusion questions by completing simple monohybrid crosses.
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.
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.
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.
Learners 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.
Pupils 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.
Tenth graders listen to a lecture and discuss how a person inherits eye color, hair color and other features. They are introduced to Punnett squares and complete several problems. They attempt to determine their own genotype.
Ninth graders complete a monohybrid cross and a dihybrid cross. In this biology lesson, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.
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, high schoolers 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.
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.
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.
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!
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.
In this genetic disorder learning exercise, students understand how genetic diseases are passed down from parents to offspring. Students use Punnett squares to explain how a disorder is inherited. This learning exercise has 10 short answer questions.
