In season 2, episode 10 marshal says something with the "shrink" that is supposed to make them both seem smart. They both say that two blue eyed parents can't have a brown eyed child. That is not true. Apparently whomever wrote this episode had genetics back in the 80s & hasn't kept current.excerpt from SOURCE: http://www.usatoday.com/tech/columnist/aprilholladay/2004-10-14-wonderquest_x.htm"Eye color is a complex trait that depends on the state of several interacting genes. The gene that usually decides the issue (blue eyes or brown eyes) is the OCA2 gene on chromosome 15. But it comes in different strengths. A person with a weak form of the OCA2 gene will have blue eyes. Likewise a person with a strong form will have brown eyes.The plot thickens, though, because an individual also has other eye-color genes that each has a say in the final eye-color outcome."gE
