  1. Agenda 1.Genetics Notes 2.Practice Problems 3. Create your monster Warm-up Football shaped heads (F) are dominant to square shaped heads (f) If two heterozygous creatures are crossed what is the chance the offspring will have a football shaped head?

  2. Genetics Incomplete Dominance And Codominance

  3. Codominance Both allele are expressed (shown) at the same time in a heterozygous individual.

  4. Codominance Examples: 1. ABO Blood Types 2. Roan Color in horses or cattle

  5. ABO Blood Types We can have : Phenotype Genotype type O blood (OO) type A blood (AA, AO) type B blood (BB, BO) type AB blood (AB)

  6. Practice Problem Bob has type B blood (BO) and Mrs. Bob has type A blood (AO). What are the possible blood types for their child?

  7. A O B o

  8. Practice Problem Bob has type B blood (BB) and Mrs. Bob has type A blood (AO). What are the chances their child will have type A blood?

  9. A O B B

  10. Roan Color Some horses can be a red color (RR), white (rr) or roan (Rr) where both red and white fur shows.

  11. Practice Problem Two Roan horses are breed together. What are the possible genotypes and phenotypes of the offspring? Give a percentage for each.

  12. R r R r

  13. Incomplete Dominance When the heterozygote phenotype is a blend of both the homozygote dominant and homozygote recessive phenotypes. Example: Snapdragon Flowers

  14. Practice Problem Snapdragons can be red (RR), white (rr) or pink (Rr). If pink and red snapdragons are crossed, what are the chances the flowers will be red? White? Pink?

  15. R r R R % Red % Pink % White
