DINNER AT HOUSTON'S
We were privileged enough to join some of my old UCLA co-workers for dinner in Century City at Houston's. We joined Mark and Gina and their newborn son Gabriel as well as Gladys and Chris. It's amazing to think that we all worked together 8 years ago as aides at UCLA and we're still such close friends.
But I have to admit that little Gabriel stole the night away. We mostly just sat there and watched him all night. He has the most beautiful blue eyes. And that made Karena wonder: If your father has blue eyes, your mother brown eyes, and blue eyes are apparently always the recessive genes, how did Gabriel end up with blue eyes? I hope some scientific people can shed some light on the subject! =)
The night was a great chance for all of us to catch up, for us to eat good food (we always order the chicken salad and the Hawaiian Rib Eye), and to see celebrities (former SNL cast member Norm MacDonald was sitting next to us).

well, the last time I took bio was about 5 years ago, but i'm pretty sure it goes like this:
the mother is a carrier of a recessive gene, but she actually displays the dominant one.
to illustrate, picture a table w/ the mother's genes on the left and the father's genes across the top, which combined will form the child's genes in the middle. the father must have dd (both recessive) in order for him to have blue eyes. this means in order for dd to show up as a possibility for the child, the mother may not be DD (because there would be 100% probability that the child would be Dd, and therefore have brown eyes). this means that the mother must be Dd in order for there to be a 50% chance of the child getting dd- blue eyes.
but of course i could be wrong.

I don't know if I'm saying this right, but here's my simple way of understanding it. I'm assuming the father is 100% on the blue eyes. In order for baby Gabriel to have blue eyes, the mother must have at least 50% blue eye gene, and the other 50% brown. That would be why she is brown-eyed, being that brown is dominant over blue. Therefore baby Gabriel blue-eye genes 75% strong, which competes with dominant brown.
