obj 9 incomplete dominance
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.
example of incomplete dominance
Example of Incomplete Dominance:
  • Red snapdragon X white snapdragon
  • All offspring are pink snapdragons
codominance
Codominance
  • Definition: a condition in which both alleles for a gene are fully expressed.
  • Ex. Blood Types
polygenic
Polygenic
  • Definition: a characterisitc of an organisms that is determined by many genes
  • Ex. Eye color, height, weight
multiple alleles
Multiple Alleles
  • Genes with three or more alleles
  • Example: Blood groups
  • A = AO, AA
  • B = BO, BB
  • AB = AB
  • O = OO
