Okay, but how would anyone even determine fingerprints are asymmetrical?
I've got a right hand that's slightly larger than my left hand; it's only
noticeable if I put them together, and even then I'm the only one that
notices. I can only imagine how the size differences may make the
fingerprint patterns between my left and right hands different.

Besides why would fingerprint asymmettry reflect differences in the brain,
why not something more major like a leg that's longer or thicker than the

Having fingerprints asymmetrical seems more minor than even the slight
asymmetry we see between the left and right side of the bodies. How many
points in a fingerprint are catalogued and compared between the two sides?

Well, to be honest with you, homosexuals don't exactly remind me of the
elephant man in terms of looks. Most of them look as symmetrical as
hetrosexuals to me. Are you absolutely sure that homosexuals are typically
going to have asymmetry? And if they do have asymmetry, and it's mostly at
the fingerprint level, how could a skewed fingerprint affect their
attractiveness ratings (let alone IQ, aggressiveness, etc.)?

It could be genetic, because we can tell the difference between male and
female (mother and father) when we are quite young. Even if that ability is
not used in the selection of sexual partners at that early age, it is used
in identifying parents and identifying between the parents.

Later we could use it for selection of sexual partners.
