I was just wondering because when I was little I had sea-monkeys and I always wondered exactly what it was that I was feeding them...

I know that DNA is a crazy thing to understand fully, because it's so complicated and intriguing. I've noticed that I'm quite attracted to white women rather than blacks (even though there are lots of black beauties out there!), just as my best friend (girl) is attracted to white guys. I've always had this, from an early age, and I can't understand it. Is there a gene that pre-determines inter-racial attraction towards a specific "race"?
