You see the words fruit fly and seem to infer that all studies are repeats of previous ones.
LOL
Please take some courses on DEVELOPMENTAL BIOLOGY
"All animals exhibit innate behaviors that are specified during their development.
Drosophila melanogaster males (but not females) perform an elaborate and innate courtship ritual directed toward females (but not males).
Male courtship requires products of the fruitless (fru) gene, which is spliced differently in males and females. We have generated alleles of fru that are constitutively spliced in either the male or the female mode.
We show that male splicing is essential for male courtship behavior and sexual orientation. More importantly, male splicing is also sufficient to generate male behavior in otherwise normal females.
These females direct their courtship toward other females (or males engineered to produce female pheromones).
The splicing of a single neuronal gene thus specifies essentially all aspects of a complex innate behavior"
No it didn't you didn't read Balakireva et al, 1998. And then you cut and paste a passage out of the summary, that you can't explain, other than "completely different area" and you've proved what?
How is it different than Balakireva et al, 1998?
Come on girl friend, you can do better.
