1. 3/5/14 Snow Day Learning goal (7.L.2.1): I will be able to explain why offspring that result from sexual reproduction (fertilization and meiosis) have greater genetic variation than offspring that result from asexual reproduction (budding and mitosis). Due Tomorrow: Quiz corrections and parent signature

2. Assignment Schedule Copy the assignments for the week into your agenda from Dr. Batten’s webpage.Dr. Batten’s http://www.gcs.k12.nc.us/Page/2600

3. Genetics Vocab Quiz Corrections – Due 3/5/14 You may get ½ credit for each missed question if your 1)Write the correct answer (on notebook paper) 2)Giving a definition for that term 3)Explanation of why your answer was incorrect 4)Parent signature on quiz Complete on notebook paper attached to your quiz and get parents signature on quiz. You WILL NOT get ½ credit if above steps aren’t done.

4. Source of Genetic Variation: Mutation & Reproduction (Recombination) As you watch and listen, write in your science notebook some sources of genetic variation (i.e. things that lead to differences in traits and individuals). http://learn.genetics.utah.edu/content/variation/sources/

5. Genetic Variation: Sexual vs. Asexual Reproduction http://www.biotopics.co.uk/genes1/asexual_and_sexual_reproduction.html In your science notebook, READ and take NOTES on the differences between asexual vs. sexual reproduction. Think about how genes (traits) are passed from parent to offspring for each. Also note some examples of each type. Which type of reproduction leads to more genetic variation and why?

6. Meiosis Watch the Meiosis (Narrated) animation and take notes on what happens to the DNA (genes) and chromosomes during each stage of meiosis. Turn on show text to help you take notes.

7. Genetics Vocabulary Flashcards due 2/28/14 Acquired Trait Acquired trait Inherited trait Sexual reproduction Heredity DNA Chromosome Gene Allele Meiosis & Stages On the FRONT Definition/characteristics: A trait or characteristic that is developed or learned through life. Traits you aren’t born with. Traits GENERALLY not controlled by DNA. Examples: Walking, speaking English, dyed hair, pierced ears, Glasses, skin cancer? On the BACK Genotypes Phenotype Dominant Recessive Gregor Mendel Pea Plants Genetic Variation Fertilization Gametes Asexual Reproduction Punnett Square Monohybrid cross Homozygous (Purebred) Heterozygous (Hybrid) Mutation Genetic Disorder Sickle Cell Anemia Hemoglobin Pedigree

8. Genetics Projects – due 3/21/14 Selective Breeding vs. Genetic Modification Corn is one of the most manipulated crops. Create a Presentation or Poster comparing traditional selective breeding vs. genetic modification (GMO). Explain the two methods and then show some specific corn varieties/cultivars that were created with each method and how. Genes associated with inherited traits We learned about several common inherited human traits. Pick at least 10 traits to research and which genes control these traits. Include pictures of the traits phenotypes as part of your presentation. You may complete as a Word document or presentation. Inheritance of Eye Color Create a Powerpoint presentation about the genetics of eye color. Include information about the different types of eye color, any genes that are associated with eye color, and how eye color is inherited. In your final slide, explain how YOU inherited your eye color. Myths of Human Genetics Dr. John McDonald from the University of Delaware has written that many of the inherited traits students learn in genetics class AREN’T really inherited in a simple dominant vs. recessive pattern that is taught. Create a Powerpoint to review his arguments and compare it to what MOST genetics students learn. Meiosis Game Create a game to help students learn the steps of meiosis. Students must answer questions about chromosomes, genes, DNA, and meiosis to advance through the stages of meiosis I and meiosis II. You win when you reach the final gamete stage. Plant Genetics Grow two different species of plants and create a digital comparison of their phenotype similarities and differences (appearance, size, growth rate, etc). Then research the genetics of the two species summarizing what you find. Include the number of chromosomes and genome size Expanded Traits Survey Create YOUR OWN survey of ten inherited traits. You may use 5 of the ones we did but must include 5 new ones. Sample at least 50 people. Write up your finds as a Research Investigation Article – but with more detailed and thorough sections than we did as a class. Genetic Disorders Create a Presentation about a specific genetic disorder. You must include the following information about that disorder: description, signs/symptoms, how it’s inherited or acquired, genes affected (including the mutation if known), incidence, and treatment. GMOs in the News Farmers and scientists use GMOs to create better crops. Write a news article picking a specific GMO and discuss the process, the benefits, and risks of using that GMO History of Genetics Create a timeline about the history of genetic knowledge starting with ancient times (ex. Biblical times) through the present. You must have at least 15 descriptions along the timeline. Selective Breeding in Dogs Dog Breeders use selective breeding to improve dog breed. Create a brochure to explain the selective breeding process and use specific examples to show how breeders have gotten new dog breeds. Pedigree Analysis Create a pedigree of at least three generations using a single inherited trait. You must use a REAL family either your own or one you research. Include a Punnett square from each generation to show how that trait was inherited (3 total) Choose ONE of the following projects to do as a summative MAJOR assessment for the Genetics Unit. Do detailed, quality work to get full credit.
