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.
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 lesson, they complete a problem to determine the correct combination of genes related to hairless dogs.
In this dihybrid cross worksheet, learners 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 worksheet, high schoolers use Punnett squares to determine the probability of genotypes and phenotypes for offspring. They also answer conclusion questions by completing simple monohybrid crosses.
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.
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.
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 instructional activity 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 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.
Help your students discover more about themselves with these great lesson ideas involving heredity, genetics, and Punnett Squares.
Learners explore experimental and theoretical probability. In this middle school data collection and analysis lesson plan, students investigate the possible combinations of genotype using a Punnett Square. Learners generate data using experimental probability and the laws of heredity.
Ninth graders determine the probability of certain traits by doing a coin toss. In this biology lesson, 9th graders differentiate genotypes and phenotypes. They use Punnett squares to predict the characteristics of offspring.
Students research genetic adaptations. In this chromosome lesson plan, students investigate dominant and recessive genes using spiders indigenous to Hawaii. Students create Punnett squares to determine the probability of passing specific genetic traits to its offspring.
In this genetic disorders worksheet, high schoolers complete punnett squares for six different human genetic disorders. They predict the outcome of the offspring including the phenotypes and genotypes of each.
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 worksheet, which comes with an answer key, will make solving Punnett Squares much less square!
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 genotypes and phenotypes of their offspring.
Young scholars simulate a Punnett square. In this dominant or recessive lesson, students explore possible outcomes of given situations. They compare and contrast homozygous dominant and homozygous recessive genes. Young scholars use graphing calculators to collect information and display it.
Seventh graders describe how the traits of an organism are passed from generation to generation. They distinguish between asexual and sexul reproduction. Students identify traits through genes and those resulting from interactions with the environment. They use simple laws of probability to predict patterns of herdity with the use of Punnett squares.
Students explore genetics through various hands-on activities. In this biology lesson, students predict the probability of offspring genotypes and phenotypes using the Punnett Square. They explain the causes of genetic abnormalities.
