Nine pages of material on inheritance make up this handout. It begins with a reading on alleles and how they can result in albinism. A chromosome modeling activity and questions follow. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn about sex determination, sickle-cell anemia, and pedigree analysis. This resource provides a variety of activities and information to support several days worth of genetics instruction.
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!
Learners observe models of the ABO blood system including erythrocytes, antigens, and antibodies. They investigate the antigens that result from certain allele combinations and move antibodies to determine whether agglutination occurs when two given blood types are mixed.
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 determine the genotypes and then solve a Punnett square for their cross. Once they predict the genotype and phenotype of the offspring, they open the egg. You will have pre-planted colored candies within the eggs according to a corresponding phenotype. This is a clever lesson for making the passing of alleles more visual.
Tenth graders discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers representing alleles to determine genotype and phenotype ratios among offspring.
In this genetics worksheet, students review vocabulary words associated with genetics including allele, gamete, hybrid, trait, and Punnett Square. This worksheet has 10 matching, 5 fill in the blank, and 10 multiple choice questions.
In this inheritance patterns learning exercise, students create a visual of a Zork using chromosome strips to represent alleles from the father and the mother to determine the traits in the offspring. Students translate the genotype to the phenotype and compare their Zork to others in the class. Students explain the differences even though the parents of all the Zorks are the same.
Here is a sharp presentation on multiple alleles using the classic blood type example. Viewers revisit codominance and dominance and learn that blood type is actually a combination of both. They use Punnett squares to solve blood type problems. They learn about agglutination and antibodies that make blood type crossing a topic of study. Follow this PowerPoint with a blood typing lab activity and more Punnett square practice.
You won't be able to use a few of the slides in this presentation since the first lists objectives not met within, and the third gives instructions to a worksheet that is not included. You will, however, find the remaining slides useful in explaining some of the genetics behind the variation in horse coat color. It is revealed that two allele pairs are responsible for the color, whereas three other pairs determine pigment distribution. Use this in a genetics unit for a biology course when teaching genetics.
In this genetics learning exercise, students complete a crossword puzzle by determining the terms associated with the 24 clues given. Students review terms such as phenotype, genotype, alleles, and Mendel.
