If you were a parent would you volunteer your child for experiments into seeing if they turn out gay?

And anyway, some scientists might shy away from an experiment that could take something like 18 years to complete - from birth right the way to adulthodd (maybe a bit further). And what about funding? I'm sure some European Scientisty place could get the funding (heck, the Swedes got funding for working out that there are 44 ways to put together an Ikea wardrobe without the instructions - only 8 of which actually work), but I'm not sure about an American Institute, especially not if it's funded by the government.
