Somatic mutation and the Antarctic ozone hole
Summary Previous studies of Antarctic clonal moss populations using RAPD markers have reported extraordinarily high levels of genetic variation. This has been claimed to reflect somatic mutation, possibly resulting from elevated UV‐B radiation. Our study used microsatellite markers to compare the ge...
