  30. Obj. 9 Incomplete Dominance • Definition: • A condition in which a trait in an individual is intermediate between the phenotype of the two parents because the dominant allele is unable to express itself fully.

  31. Example of Incomplete Dominance: • Red snapdragon X white snapdragon • All offspring are pink snapdragons

  32. Codominance • Definition: a condition in which both alleles for a gene are fully expressed. • Ex. Blood Types

  33. Polygenic • Definition: a characterisitc of an organisms that is determined by many genes • Ex. Eye color, height, weight

  34. Multiple Alleles • Genes with three or more alleles • Example: Blood groups • A = AO, AA • B = BO, BB • AB = AB • O = OO

  35. Practice Problems
