6. Engage Eagle Zone- Pick up the pages from the front and begin working the first page (front and back) with your partner Looking at Your Traits You and your groups will be looking at each other to determine whether you are dominant or recessive for the following traits.

7. Eagle Zone Today we will explore the principles of dominance and recessiveness. In order to do so, you must understand the following terms: Dominant, recessive, genotype, phenotype Using your own explanation, give the meaning of these words (you should already have them defined from your HMWK page)

8. Principle of Dominance or Recessiveness Traits found in humans

9. Tongue Rolling

10. Earlobes

11. Earbump Often called Darwin’s Ear Bump

12. Widow’s Peak

13. Hitchhiker’s Thumb

14. Polydactyly

15. Syndactyly Feet

16. Syndactyly Hands

17. Severe Syndactyly

18. Syndactyly Surgery

19. Cleft Chin

20. Clockwise Hair Whorl

21. Eagle Zone 1. Get out vocabulary homework and the review from last week. Place it in the corner of your desk 2. Review for your quiz 10 minutes, then we will take the quiz

22. Explore/Explain Describing Your Traits Using the information provided, determine your phenotype and genotype for the identified traits. Use the information in the binders to help you answer the questions on the guided notes page We will discuss the questions in groups of 4 and then as a class

23. Eagle Zone Come in and continue working on your Bug Lab with your partner. You will have 20 minutes to complete the lab when the bell rings.

24. Elaborate Bugs, Bugs, Bugs Genes for traits are encoded and arranged linearly on structures called chromosomes found in the nuclei of most cells. When organisms reproduce, the resulting offspring should receive an equal number of chromosomes from the mother and the father. In this activity you use the chromosomes and Bug Traits Key to determine the genotype and phenotype of the offspring.
