Students view a simple ABO blood system for the introduction of this subject using concrete models of eythrocytes (red blood cells, or RBC's), antigens, and antibodies. They can physically see the antigens that result from certain allele combinations and can move antibodies to determine whether agglutination occurs when two given blood types are mixed.
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!
Students 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 instructional activity for making the passing of alleles more visual.
Students investigate how selective forces like food, predation and diseases affect evolution. In this genetics lesson, students use red and white beans to simulate the effect of malaria on allele frequencies. They analyze data collected from the experiment and answer analysis questions at the end of the lab.
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.
After learning to calculate probabilities for single examples of genetic crosses in a previous lecture, students are exposed to the concept that allele and genotype frequencies in a population remain in constant equilibrium. A reasonable grasp of math is necessary to comprehend this presentation.
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 are a great recap of all concepts pertaining to this topic. There are some gaps where they can fill in topic words and definitions.
In this basics of genetics worksheet, students review the concepts of genetic inheritance by writing the alleles for genetic traits inherited in offspring. They identify dominant and recessive traits given allele pairs, answer five questions about genetic crosses, practicing monohybrid and dihybrid crosses, and complete sex-linked and incomplete dominance crosses.
Again, the basis for trait inheritance and the impact of alleles in phenotypes was covered in previous videos. This presentation focuses on gender and the likelihood of traits if they are sex-linked. Sal tells a great anecdote about where the blame should have been placed for Henry VIII's female offspring.
In this genetics worksheet, students use an imaginary species and a list of genetic traits and the alleles that code for each trait to determine the genotype and phenotype probabilities of offspring. Students complete nine monohybrid crosses to determine the probabilities of the offspring.
Blood types and transfusions are explained in reading passages at the top of the worksheet. A chart of blood type compatibility is also provided. Biology students answer comprehension questions and then exercise critical-thinking skills to apply what they have learned to different scenarios. Finally, they solve a Punnett square for the three blood type alleles. This is a reliable resource.
In this inheritance patterns worksheet, 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. Kids 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.
Tenth graders work in teams to order events of DNA transcription and translation protein synthesis. In the second lesson, they put the steps of mitosis and meiosis in order using a concept map poster. They use modeling clay to create models of cells undergoing these changes. In the third lesson, 10th graders create Punnett squares, and participate in an interactive lecture on genes, alleles, traits and geno/pheno types.
Students study the number of chromosomes in the body cells, sperm cells, and egg cells of humans. They define allele, and examine the difference between dominant and recessive alleles. They complete an activity with jelly beans that represent genes for several human traits.
