  1. Agenda • Bell Ringer • College • Notes • Question of the Day • Paper Pets!

  2. Virginia Polytechnic Institute and State University • Location: Blacksburg, VA • Size: 23,690 students • 26 – 30 average ACT • Admitted: 67% • Mascot: Hokies

  3. Colors: Maroon and orange • Famous for: Great engineering and architecture • One of three schools with a cadet corps • Virginia Tech massacre – 32 • “Hoki, Hoki, Hoki, Hy. Tech, Tech, V.P.I.”

  4. Agenda • Bell Ringer • College • Notes • Question of the Day • Paper Pets!

  5. Agenda • Bell Ringer • College • Notes • Question of the Day • Paper Pets!

  6. GENOTYPE VS. PHENOTYPE • Aa, Bb, cc, dD, eE, FF, Gg, Hh, ii, JJ, kK, ll, MM….OH MY!!! April 2, 2013

  7. By the end of the day… • Achievers on the ROAD to college will know the difference between a phenotype and a genotype. • Achievers on the ROAD to college will be able to predict a phenotype using a given genotype. • Achievers on the ROAD to college will be able to answer our question of the day!!

  8. QUESTION OF THE DAY!! • How is the way that we look (phenotype) related to our DNA (genotype)? • How do we get from a strand of DNA to a blonde haired, green eyed Ms. O’Hara?

  9. How organisms look vs. How their genes look? • The alleles for the dimple trait are written above each child below. • DDDddDdd • Which kids have dimples and which ones don’t?

  10. GENOTYPE • The way the (1)alleles are written is called its genotype. • DD, Dd, dd are all genotypes for dimples • (2)AA, Aa, AABbare all examples of genotypes

  11. PHENOTYPE • What an organism (3)looks like • It is the genotype expressed in a way we can observe. • In our example, dimples or no dimples give the phenotype • (4)Tall, green seeds, brown hair are all examples of phenotypes • Phenotype = Physical

  12. There are 2 dimple phenotypes: Dimples No Dimples

  13. BUT. There are 4 dimple genotypes. DD DddDdd

  14. Phenotype or Genotype?? • Tt GENOTYPE

  15. Phenotype or Genotype?? • Tall PHENOTYPE

  16. Phenotype or Genotype?? • Ll GENOTYPE

  17. Phenotype or Genotype?? • Wrinkly PHENOTYPE

  18. Phenotype or Genotype? • Big Lips PHENOTYPE

  19. HOMOZYGOUS • Organism that has (5)two identical alleles for a given trait • AA, aa, BB, bb are all examples ((6)Bothletters are either capital or lowercase)

  20. HETEROZYGOUS • Organism that has two (7)differentalleles for the same trait • Called a (8)hybrid for that trait • Aa, Bb are examples (one letter is a capital and one is lowercase)

  21. Homozygous or Heterozygous?? • HH HOMOZYGOUS

  22. Homozygous or Heterozygous? • Kk HETEROZYGOUS

  23. Homozygous or heterozygous? • nn HOMOZYGOUS

  24. Homozygous or heterozygous?? • Jj HETEROZYGOUS

  25. ROAD check • Remind me, what does phenotype mean? • What does genotype mean?

  26. Genotype and Phenotype BB or Bb=brown eyes bb= blue eyes With genotype BB, what phenotype would we see? Brown eyes

  27. Genotype and Phenotype SS or Ss= brown skin ss=white skin • With genotype Ss, what phenotype would we see? Brown skin

  28. Genotype and Phenotype LL or Ll=big lips ll=small lips What would the genotype be for big lips?? LL or Ll

  29. Genotype and Phenotype SS or Ss=brown skin ss=white skin • With phenotype white skin, what genotype(s) could we see? ss

  30. Genotype and Phenotype DD or Dd= dimples dd= no dimples If you notice your little brother has no dimples, what must his genotype(s) be?? dd

  31. Agenda • Bell Ringer • College • Notes • Question of the Day • Paper Pets!

  32. QUESTION OF THE DAY!! • How is the way that we look (phenotype) related to our DNA (genotype)? • How do we get from a strand of DNA to a black haired, green eyes? • BB or Bb = brown hair, bb = blonde hair • GG or Gg = green eyes, gg = blue eyes

  33. Agenda • Bell Ringer • College • Notes • Question of the Day • Paper Pets!

  34. Independent Practice • You are going to create a Paper Pet using a genotype that is given to you. • Each person in your group will have a different genotype (SO DON’T TRY TO COLOR EXACTLY WHAT YOUR NEIGHBOR DOES  )

  35. INDEPENDENT PRACTICE CONTINUED… • You are going to use the chart on your paper to help you figure out what phenotype corresponds to your given genotype • You will then draw or color those characteristics on your paper pet.

  36. On the back of your paper pet: My paper pet had these phenotypes: ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________
