  1. Chapter 11.2 and 11.3: Complex Inheritance and Karyotypes http://faculty.irsc.edu/FACULTY/TFischer/bio%201%20files/bio%201%20resources.htm

  2. Incomplete Dominance: The heterozygous phenotype is an intermediate phenotype between the two homozygous phenotypes. Codominance: Both alleles are expressed in a heterozygous condition. http://weloveteaching.com/2011/genetics/genetic.html http://www.arrowkranch.com/Ranch_tour/New_pictures/roan_cow.gif

  3. Sickle Cell Disease is actually codominant. If a person possesses both genes, some of their red blood cells will appear normal and others will appear sickled. Blood types are also codominant. http://www.biologycorner.com/anatomy/blood/notes_blood_disorders.html
