It doesn't
scientifically prove that gay men and lesbians are
"hardwired" with their sexual orientation before birth, but
a new study released Friday on the genes and sexual
behavior of fruit flies is rocking the scientific community. Yes, you heard that right. Fruit flies could be
instrumental in helping scientists understand if there
is a "gay gene." Researchers at the Institute of Molecular
Biotechnology at the Austrian Academy of Sciences in
Vienna genetically altered a female fruit fly. When it
was released into an observation chamber it took on the
sexual personality of a male. The female tapped
another female fruit fly on the leg, played her a
mating song with its wings, and then licked her. That one male gene is apparently by itself
enough to create patterns of sexual behavior--a kind
of master sexual gene that normally exists in two
distinct male and female variants, according to The New
York Times, which first reported the story. The newspaper also reported that in a series of
experiments, the researchers found that females given
the male variant of the gene acted exactly like males
in courtship, madly pursuing other females. Males that
were artificially given the female version of the gene
became more passive and turned their sexual attention
to other males. ''We have shown that a single gene in
the fruit fly is sufficient to determine all aspects
of the flies' sexual orientation and behavior,'' said the
paper's lead author, Barry Dickson, senior scientist
at the institute. ''It's very surprising. What it
tells us is that instinctive behaviors can be
specified by genetic programs, just like the morphologic
development of an organ or a nose.''
