A study at the University of Helsinki, cited In the New York Times science
section 3-4-03, established that ants workers favor offspring in the colony
more closely related.  The researchers said that apis mellifera is the only
other insect to show such nepotism.  So how do bees show preference for,
say, sisters over half-sisters?  I would be interested in references to
studies of this behavior in bees.
