Notes multiple alleles

  1. 1. Bell Work• Study for the quiz! Look over your Interactive notes (pg 12-13) and your Incomplete/Codominance worksheet
  2. 2. Notes: Multiple Alleles (pg 14)
  3. 3. Notes: Multiple Alleles (pg 14)• Multiple alleles = Traits controlled by more than two alleles
  4. 4. Example: Rabbits• C = agouti (dark gray)
  5. 5. Example: Rabbits• C = dark gray• cch = chinchilla (light gray)
  6. 6. Example: Rabbits• C = dark gray• cch = chinchilla (light gray)• ch = himalayan (white with black points)
  7. 7. Example: Rabbits• C = dark gray• cch = chinchilla (light gray)• ch = himalayan (white with black points)• c = white
  8. 8. Example: Rabbits• C = dark gray• cch = chinchilla (light gray)• ch = himalayan (white with black points)• c = white• Dominance: C>cch>ch> c
  9. 9. Genotypes• White: cc
  10. 10. Genotypes• White: cc• Himalayan: chch or chc
  11. 11. Genotypes• White: cc• Himalayan: chch or chc• Chinchilla: cchcchor cchch or cchc
  12. 12. Genotypes• White: cc• Himalayan: chch or chc• Chinchilla: cchcchor cchchor cchc• Gray: CC or C cchor C chor Cc
  13. 13. Practice problem (pg 15)• Draw the Punnett square and give the phenotype ratios for the following cross: C cchx chch
  14. 14. Output Activity (pg 15)• Make up a multiple alleles problem that requires a Punnett square to solve. You must make up a NEW trait with 4 different alleles, explain the phenotypes, and say which traits are dominant to which.
