Principle Co-ordinates Analysis (PCO) of allozyme allele frequencies for Yilgarniella sturtensis, showing mtDNA haplogroup and allozyme group membership of individuals. Three genetic populations were found; haplogroup 1a/allozyme group 1, haplogroup 1a/allozyme group 2, haplogroup 1b/allozyme group 2. Allozyme groups are specified by a dotted line. The relative PCO scores have been plotted for the first (X-axis) and second (Y-axis) dimensions.
