Unexpected Eye Color Inheritance

Postby michaelg » Sun Aug 21, 2011 11:30 pm

I have a genetics mystery in my family, though perhaps it has an easy answer. A family member has brown eyes, yet both her parents have blue eyes. (Note, they are definitely the blood parents.) It is my understanding that blue eyes are recessive to brown eyes, so the parents would have to be "bb" and "bb", yet their offspring is "B_". How can this be? Thanks!
