4. Objectives • I can solve a puzzle using my knowledge of Mitosis and Meiosis.

5. Mitosis/Meiosis Review Activity • You and a partner will get an envelope • Goal: You and your partner will work together to properly connect the sides of each square piece. (the words/definitions must match up!) • Winner will receive 8 tickets each and a special surprise 

6. Star Quiz 13 • When you are done, turn in work and you may begin on your homework.

7. Objectives • I can identify genotypes and phenotypes. • I can classify alleles as being dominant or recessive. • I can determine whether the dominant or recessive phenotype will be shown in a given situation.

8. Intro to Genetics

9. How do you know what your child will look like? Why do people look like their parents? What are some characteristics you could share? Complete the QUICK WRITE on your guided notes

10. Trait: A characteristic (what you look like) Examples: hair color, eye color

11. You inherityour traits from your parents

12. Genetics: The study of how traits are passed from one generation to the next

13. Gene: A piece of DNA that controls a trait

14. Each gene comes in 2 versions (types)

15. Allele: Version (type) of a gene

16. You inherit 2 alleles foreach gene:1 from mom, 1 from dad

17. An allele is written as aletter Example:T, t, B

18. Genotype: Your genes for a trait Examples: BB, tt, Tt

19. Phenotype: Your trait (what you look like) Examples: brown hair, blue eyes, red flowers PHenotype = PHysical characteristics

20. Think: genotype or phenotype?

21. BB

22. Brown eyes

23. Curly hair

24. Bb

25. Blue Eyes

26. Hh

27. There are 2 kinds of alleles:dominant and recessive

28. Dominant: Allele that is always shown Written as: a capital letter Example: B, T, R

29. Recessive: Allele that is ONLY shown if it’s with another recessive allele Written as: a lowercase letter Example: b, t, r

30. i.e. brown eyes (B) are dominant to blue eyes (b):

31. In flowers, the allele for pink flowers (P) is dominant over the allele for purple flowers (p) • Madison finds a purple flower in her garden. What is the genotype of that flower? • Marco finds a pink flower to give to his girlfriend. What is the genotype of his flower?

32. Panther Pass Think: dominant or recessive? The Panther Pass is to be done independently and silently.

33. Think: dominant or recessive?1. B2. Always shown3. h4. T 5. Only shown when it is with another recessive allele 6. s

34. What is the difference between a dominant and recessive trait? Explain • In zebras, the allele for skinny stripes (X) is dominant to the allele for fat stripes (x). What is the genotype of a zebra with fat stripes?

35. Think: dominant or recessive?1. B2. Always shown3. h4. T 5. Only shown when it is with another recessive allele 6. s

36. Think: dominant or recessive?1. B - Dominant2. Always shown - dominant3. h - recessive4. T - dominant 5. Only shown when it is with another recessive allele - recessive6. s - recessive

37. What is the difference between a dominant and recessive trait? Explain Dominant traits are always shown and recessive traits are only shown when paired with another recessive allele 7. In zebras, the allele for skinny stripes (X) is dominant to the allele for fat stripes (x). What is the genotype of a zebra with fat stripes? xx
