My husband has grey eyes, and my mother green eyes, so it's not surprising that, while I have brown eyes, my son has light eyes.
What is surprising is that they're blue. Nobody can remember a blue eyed child in the family -- obviously something to do with having a double recessive gene.
Blondness also runs in both families, but the type of blondness where the young children are tow-headed but darken as they get older.
Sometimes randomness is just randomness.
My oldest son looks like the milkman.
How's that for randomness.
