blue/brown eyes

[MICHAEL P. KOLOTILA]

Hi Bionetters,
A quetion arose in my intro biology class about eye color that I don't have a
good answer for or at least one that I can back up with documentation.  What is
the reason that some individuals have one blue eye and one brown eye?  I
thought that it may be due to chromosomal inactivation, but that would probably
only work for females if eye color is sex-linked.  Anyone out there have an
answer?  Please on Bioforum as I am sure that other people are losing sleep
over this too. ;-)
Thanks in advance.
Michael
