Maybe I’m a little slow. Are you saying that you know a researcher that I can fire a question to in e-mail?

But the other items in your list don’t always show up as well.

To be honest I’m not sure if that is accurate. I think those show up every time in any sort of broad sample.

In ten years if we’re still posting on this board that list is going to be much bigger. Heck, the whole thing could be figured out by then. Somebody is bound to inject gay sheep with the juice that turned bi fruit fly’s straight. If it works in sheep the whole mystery is over.

Ya know, I thought about the Fraternal Birth Order Effect but didn’t include it only because sometimes it doesn’t show up.

But the other items in your list don’t always show up as well. I just thought that was worth pointing out – its a good list though 🙂 It might also be worthwhile to mention that your list only shows us what we currently know – or think we know 🙂

I never suggested that we didn’t have clues – I believe if you re-read my post you will see that I said that scientists are currently following many of those clues that point to a genetic component for homosexuality 🙂

Ya know, I thought about the Fraternal Birth Order Effect but didn’t include it only because sometimes it doesn’t show up. But you are right. I can see why it could be considered a good clue. Researchers find it often enough that if I had to flip a coin I’d guess there is something to it.

I believe that fraternal birth order can be added to your list. The findings seem consistent.

People of ANY age can have genetic disorders when the disorder is due to genetic damage. I meant healthy genes that pass from generation to generation.

More to the point, the variant’s influence on obesity appears to be strongest during childhood and diminishes after age 45.

Yep, that’s the way a lot of things work. I guess I never really thought that scientists weren’t taking that into account. OOPS! 😎

The other day I read about a gene that correlated with a common type of macular degeneration. The disorder didn’t usually happen but when it did it hit older people. People who didn’t have the gene (which was super common) rarely had macular degeneration. I think like a quarter of the population had this gene or thereabouts.

Side Note:

Most people don’t have genetically triggered health problems until the age of 60 +/-. It isn’t that genes don’t play a role, but before that age most common disorders require environmental input. Rare disorders (1 in 10,000), and on occasion geographically specific disorders are a different story. All bets are off for those.

Genetic effects for complex traits can vary by age.

but we do have clues

Clue #1 Repeated findings of weak but still present identical twin concordence.

Clue #2 About a zillion studies that show that gay people are more likely to be left handed.

Clue #3 Increased incidence of gender a-typical behavior among boys who grow up to be gay.

There is a lot of other stuff but I’m not sure if any other findings have been studied as thorougly as these three. We can pretty much count on these to hold up.
