  1. #3 – List EACH trait you thought the Potato Head child would have: • Eye Color • Ear Color: • Nose Color: • Lip Color: • Skin Color:

  2. What does all this mean???

  3. Gym Sock Genetics

  4. Gym Sock Genetics • How many socks are given to a child by a parent? • One from each parent

  5. Gym Sock Genetics • Dominant Trait: • Appears if one or both parents passes it. • Written as a CAPITAL letter/allele

  6. Gym Sock Genetics 3. What color represents the dominant trait? Red represents the dominant trait. (R)

  7. Gym Sock Genetics • Recessive Trait: • Appears ONLY when both parents pass it. • Written as a lowercase letter/allele

  8. Gym Sock Genetics 4. What color represents the recessive trait? Whiterepresents the recessive trait. (r)

  9. Gym Sock Genetics Genotype: TWOinheritedalleles/letters (different forms of the gene)

  10. Gym Sock Genetics 5. What genotypes make red? RR and Rr

  11. Gym Sock Genetics 6. What genotypes make white? rr

  12. Genotypes always come in pairs Why???? Inherit from one allele from EACH parent

  13. Gym Sock Genetics Heterozygous (hybrid): Different alleles (Rr) for a particular trait.

  14. Gym Sock Genetics Homozygous (purebred): Same alleles (RR and rr) for a particular trait.

  15. Gym Sock Genetics 7. List the genotype of a heterozygous individual. Rr (different alleles = capital letter and lowercase letter)

  16. Gym Sock Genetics 8. List the two possible genotypes of a homozygous individual. RR and rr (same alleles = two capital letters or two lowercase letters)

  17. Gym Sock Genetics 9. Which of the above genotypes is the homozygous dominant? RR

  18. Gym Sock Genetics 10. Which of the above genotypes is the homozygous recessive? rr

  19. Gym Sock Genetics • Phenotype: • An organism’s appearance • What you see

  20. CFU…. What determines the phenotype?? (HINT: Think of 2 letters!!!) A GENOTYPE

  21. Gym Sock Genetics 11. What is the phenotype of the homozygous dominant genotype? Red (RR)

  22. Gym Sock Genetics 12. What is the phenotype of the homozygous recessive genotype? White (rr)

  23. Gym Sock Genetics 13. What is the phenotype of the heterozygous one? Red (Rr)

  24. Gym Sock Genetics 14. What does the sock represent in our model? Genes  Alleles

  25. Gym Sock Genetics 15. What do the two different colors of socks represent? Different alleles

  26. What does all this mean???

  27. Review Questions • phenotype; genotype • alleles • traits or characteristics • the dominant trait • Each plant had two alleles for each characteristic, and each parent gives one allele to the offspring which may be dominant or recessive.
