High schoolers 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.
Young scholars 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.
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.
A brief animation introduces heredity to your beginning biologists. They will meet Gregor Mendel's green and yellow peas, dominant and recessive traits, homozygous and heterozygous alleles, and Punnett squares. In this cartoon animation, the peas all have arms, legs, and facial features. Seeing the little pea families makes an endearing introduction to heredity concepts!
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all the difference in survival when the landscape changes drastically. After watching the video, high schoolers take a look at the Hardy-Weinberg theorem, perform some calculations regarding the frequency of heterozygous genotypes in the rock pocket mouse population, and answer some short analysis questions.
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.
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.
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 investigate how Hardy-Weinberg Equilibrium is established and what assumptions and conditions are necessary to reach Equilibrium. They model alleles using materials such as index cards, M & M's and goldfish.
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.
For 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.
High school biology learners simulate gene flow within a population of fish. They hold colored fish cards as identification and carry "Good & Plenty®” candies to represent alleles, the recessive homozygous of which is lethal. You will need to construct the fish cards and set obstacles up around the room for fish to swim around.
Tenth graders work in teams to order events of DNA transcription and translation protein synthesis. In the second activity, 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 activity, 10th graders create Punnett squares, and participate in an interactive lecture on genes, alleles, traits and geno/pheno types.
Students explore probability. In this secondary mathematics lesson, students examine genetic problems caused by inbreeding. Students calculate the probability that a child will receive the same allele from the grandfather through both the mother and the father.
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.
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.
Eighth graders explore how different organisms pass their traits to their offspring. In this life science lesson, 8th graders differentiate recessive and dominant alleles. They predict the phenotype based on the genotype of an organism.
Students are presented with a scenario that requires them to electrophoreses human hemoglobin samples in order to confirm a diagnosis of sickle cell anemia and/or to determine whether individuals in the scenario are carriers of the sickle cell allele. They are asked to analyze the separation of the different types of hemoglobin on the gel.
