Diversity statistics by structure cluster. A. Samples grouped by majority allocation in the K =6 model. B. Samples grouped by majority allocation in the K=2 model. Diversity statistic estimates are given correct to 2 d.p

	Number of samples with highest proportional allocation to that cluster	Diversity measures (means across 16 loci)
Cluster		Number of alleles	Frequency of most common allele	Gene diversity	PIC
