多伦多大学科学家用果蝇创造同性“性海啸”
http://www.lbnelert.com/wp-content/themes/default/images/lbnelert/091016_scientists.jpgSCIENTISTS CREATE 'SEXUAL
TSUNAMI': Scientists at the
University of Toronto found that by genetically tweaking fruit
flies so they failed to produce a particular type of pheromone or
odour, it turned them irresistible to their species. Professor Joel
Levine, who led the study, removed the cuticular hydrocarbon
pheromone, used by the flies to communicate. They discovered that
when the pheromone was removed, it created a "sexual tsunami" where
the bugs proved attractive to one another, regardless of sex. The
research found that male fruit flies with no history of
homosexuality attempted to mate with their pheromone-free males,
according to the research published in journal
Nature.
