The brains of males and females, and how they use them, may be far more different than previously thought, at least in the fruit fly Drosophila melanogaster, according to research funded by the Wellcome Trust. In a paper published today in the journal Nature Neuroscience, researchers from the University of Glasgow and the University of Oxford, have shown that the gene known as 'doublesex' (dsx), which determines the shape and structure of the male and female body in the fruit fly, also...

CORVALLIS, Ore. -- New research has shown that the manipulation of a single gene in female fruit flies can make their sexual behavior resemble that of males, in a study that demonstrates the power of individual genes and the profound impact of genetics on complex sexual behavior. The findings were published today in the journal Nature by scientists from Oregon State University, Stanford University and Brandeis University. The research was done with the gene "fruitless," which is present...

Turning on a single male-specific gene produces a female fruit fly that displays male courtship behaviors: chasing other females, tapping their abdomens and performing wing-beating love serenades. The results, published in the June 15 online edition of the journal Nature, show that a single gene can determine how females and males detect and respond differently to sexual cues. ''In these experiments we see all the steps of the male courtship ritual you could physically expect a female fly to...

A male fly's sexual courtship of a female fly is a complicated business of tapping, singing, wing vibration, and licking, but a single gene is all that is needed to produce this complex behavior, according to new research published in this week's issue of the journal Cell. The gene encodes the Fruitless protein. Male and female flies carry different versions of the fruitless protein, as a result of sex-specific splicing of the mRNA. The male form of Fruitless is critical for the male...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
