  1. Incomplete DominanceCodominanceMultiple Alleles In a nutshell!

  2. WW = purple Ww = purple ww = white Review: Dominant/Recessive • One allele is dominant over the other (capable of masking the recessive allele)

  3. Review Problem: Dominant/Recessive • In pea plants, purple flowers (W) are dominant over white flowers (w) show the cross between two heterozygous plants. GENOTYPES: • ____________________ • ____________________ PHENOTYPES: -___________________ - __________________

  4. RR = red rr = white Rr = pink Incomplete Dominance • A ______ (new) ________ appears in the ____________ condition. • Flower Color in 4 O’clocks

  5. Problem: Incomplete Dominance • Show the cross between a pink and a white flower. GENOTYPES: • _________________ • _________________ PHENOTYPES: • _________________ • _________________

  6. NS = some of each SS = sickle cells NN = normal cells Codominance • In the _____________ condition, _____ _______ are expressed _________ • Sickle Cell Anemia in Humans sick

  7. Problem: Codominance • Show the cross between an individual with sickle-cell anemia and another who is a carrier but not sick. N S GENOTYPES: • _________________ • _________________ S S PHENOTYPES: - _________________ - _________________

  8. Multiple Alleles • There are ________________________________________________ • Blood type in humans • Blood ______? • Type __, Type _, Type __, Type _ • Blood ______? • A, B, O (in book – IA, IB, I)

  9. Rules for Blood Type • A and B are _________ • AA = Type ___ • BB = Type ___ • AB = Type ___ • A and B are _________ over O • AO = type ___ • BO = type ___ • OO = type ___

  10. Problem: Multiple Alleles • Show the cross between a mother who has type O blood and a father who has type AB blood. A B GENOTYPES: - _________________ - _________________ O O PHENOTYPES: - _________________ - _________________

  11. Problem: Multiple Alleles • Show the cross between a mother who is heterozygous for type B blood and a father who is heterozygous for type A blood. GENOTYPES: A O • ___________________ • ___________________ • - __________________ B O PHENOTYPES: • ____________________ • ____________________ • - ___________________
