Study turns human genetics on its head (less monkey...more variations)

...Using new technology to study the genomes of 270 volunteers from four corners of the world, researchers have found that while people do indeed inherit one chromosome from each parent, they do not necessarily inherit one gene from mom and another from dad.

One parent can pass down to a child three or more copies of a single gene. In some cases, people can inherit as many as eight or 10 copies....

All this confusion over eye color is enough to Make My Brown Eyes Blue!

The milkman

My mind went to the same place, but the punchline needs to be updated:

The UPS man.

Studies I've seen over the years suggest that about 15% of all fathers listed on birth certificates are not the biological parents...i.e. some hanky panky was going on. Certainly not suggesting it happened in this instance...but it is more common than many think. The bad boy sows his wild oats and Mr. Nice Guy gets to raise the kid in ignorance.

The mailman?

Ha ha! You funny.

Yes, I had them mixed up. See my post #51.

My husband has grey/blue eyes, I have very blue eyes. My older daughter has brilliant, sapphire eyes and my younger has green/brown eyes. Wierd huh? My mom has brown eyes, as does his mom, all other grand parents are blue or grey. We always assumed she picked up the brown from a grandparent.

When our kids were little, people thought they were
adopted.......my husband is half italian, with black
hair and golden brown eyes, I am a brown-eyed brunette.
Our son and daughter were both very blonde with blue,
blue eyes (which have become green in their "old age").
Maternal grandpa, and paternal grandma both have striking blue eyes.

"I just want to know about the gene pool from which Janet Reno came."

I believe that "pool" is known as The Black Lagoon.

Two blue eyed parent can NOT have a brown eyed daughter.

That's the old conventional wisdom. It's turning out that eye color inheritance is much more complicated than the simple dominant brown vs. recessive blue paradigm. In fact, blue-eyed parents CAN produce brown-eyed offspring (even in the absence of adultery), albeit this is fairly rare.
