Random mating of the giant clam, Tridacna gigas
, over 2000 km within a highly connected reef complex, the Great Barrier Reef, was inferred from allozyme data (Benzie and Williams 1992b), but significant genetic differentiation was later detected between populations from the Great Barrier Reef, Melanesia and Micronesia (Benzie 1993; Benzie and Williams 1995).
