Phantom hitch-hikers mislead estimates of genetic variation in Antarctic mosses

Previous studies of Antarctic mosses employing RAPDs have reported extraordinarily high levels of genetic variation, even within a single clump of moss. This is unexpected given their extreme isolation in Antarctica and lack of sexual reproduction. We offer an alternative explanation: that unusually...
