Recently on MNBC on cable there was a story of man, whom has blue eyes
and wife whom has blue eyes, had a child with brown eyes. The 2 couples
divorced (wife up and left w/ child while husband was out of town)She
sued him for child support. The man remarried 2 years later. One day
the mother of the child showed up at ex-husband door to drop off kid
for weekend visitational rights. The new wife notice something that
shocked her. The child with brown eyes from blue eyed dominant parents.
Medelain laws states...no issues bearing brown eyes from parents with
dominate blue traits can have brown eyes. No exceptions !
The new wife had Medelian's Laws of Inheritance from her college days
and read up on this. She insisted that her husband take a DNA test with
his son. The test results: 99.99 % not his child. He back sued the ex-
wife. He won. It is genetically impossible for 2 dominate blue-eyed
parents to have brown eyed children. But, 2 brown eyed parents can have
a blue-eyed child. The author of this study from below has a twin. He
probably needs to have a DNA tests to show proof that his parents are
biologically his. I doubt it though. SURPRISE !! :)
