If I get my DNA sequenced at 23andMe or DecodeMe, what information do I get? Is my privacy safe?

If my parents do it too, will it tell me where recombination happened in each chromosome? Btw, does anyone know of a visualization of the chromosomes showing some genes (and corresponding phenotypes)?

Kinda like this but more general-purpose and for

I've totally been pondering this very subject!! I had been playing with a theory last year about whether men vs women should preferentially be attracted to someone who stands out genetically in their population.... and then lately, puzzled by the fact that my baby still seems to have very blue eyes at 4 months (I know it's not settled 'til 6, but I still expected to see them start to change by now!) despite my husband being Indian, I'd been wondering quite how it actually worked, including how you end up with hazel.

Thanks for posting a synopsis of just the info I'd been wanting but not yet taken the time to dig up myself!

(of course, now that I know someone got a publication out of a simple idea I'd been playing with I'm kind of jealous...)

Your baby must be 6 months old by now. What color are they now?

You're right on time - I'm impressed.

And... they're still blue! They're sort of a blue/grey... but definitely not brown.

I've met a surprising number of half-Indian people with blue eyes. At CMU, I remember one of them who was 100% Indian.

I hear about it for some north Indians... but it's awfully strange for a south indian. Although there are people with hazel eyes in my husband's family.

They're sort of a hazel-ish brown. Not a normal brown, but definitely not blue, at this point.

Number 2 is currently cooking - we'll see what color we get this time we roll the dice =)
