  1. 3/6/14114th Day of School 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 variationthan offspring that result from asexual reproduction (budding and mitosis). Due Today:Quiz corrections and parent signature Evening Assignment: Finish Meiosis diagram

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

  3. You may get ½ credit for each missed question if your Write the correct answer (on notebook paper) Giving a definition for that term Explanation of why your answer was incorrect 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. Genetics Vocab Quiz Corrections – Due 3/5/14

  4. 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). Source of Genetic Variation: Mutation & Reproduction (Recombination) http://learn.genetics.utah.edu/content/variation/sources/

  5. http://www.biotopics.co.uk/genes1/asexual_and_sexual_reproduction.htmlhttp://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? Genetic Variation: Sexual vs. Asexual Reproduction

  6. McDougall pgs. C102-103 Key Terms Homologous Chromosomes (from father & mother) Sister chromatids (replicated chromosomes) http://www.phschool.com/science/biology_place/labbench/lab3/homologs.html

  7. http://www.phschool.com/science/biology_place/labbench/lab3/homologs.htmlhttp://www.phschool.com/science/biology_place/labbench/lab3/homologs.html http://kids.britannica.com/comptons/art-90111/A-homologous-pair-of-chromosomes-consists-of-one-chromosome-from Homologous Chromosomes (from father & mother) Sister chromatids (replicated chromosomes) Meiosis: process of cell division where DNA is replicated (copied) then separated and divided twice to produce new cells called gametes (reproductive cells) Key Terms

  8. Read McDougall pages C120-120 about Meiosis. Then watch the Meiosis animation detailed on the next slide. Use the two resources to create a labeled diagram showing and describing what happens to the chromosomes in each stage of meiosis. Meiosis

  9. 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. http://www.sumanasinc.com/webcontent/animations/content/meiosis.html Meiosis

  10. On the BACK 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? Acquired Trait Genotypes Phenotype Dominant Recessive Gregor Mendel Pea Plants Genetic VariationFertilization Gametes Asexual Reproduction Acquired trait Inherited trait Sexual reproduction Heredity DNA Chromosome Gene Allele Meiosis & Stages Punnett Square Monohybrid cross Homozygous(Purebred) Heterozygous (Hybrid) Mutation Genetic Disorder Sickle Cell Anemia Hemoglobin Pedigree Genetics Vocabulary Flashcards due 2/28/14

  11. 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. Genetics Projects – due 3/21/14

  12. This evening… • Finish Meiosis Diagram • Test Mondayover • Traits • Punnett squares • Pedigrees • Meiosis Evening Assignment
