|deme (dēm) Pronunciation Key
A small, locally interbreeding group of organisms within a larger population. Demes are isolated reproductively from other members of their species, although the isolation may only be partial and is not necessarily permanent. Because they share a somewhat restricted gene pool, members of a deme generally differ morphologically to some degree from members of other demes. See also population.
