Population structure in Yilgarniella sturtensis. (a), Distribution of mtDNA haplogroup 1a (light) and haplogroup 1b (dark) across the bore hole grid. (b), Results of GENELAND analysis of population structure in allozyme allele frequencies, as a map of posterior probabilities of population membership (number of populations=2). Lighter areas correspond to higher probability to belong to allozyme group 1, and bores sampled are indicated by black dots.
