Genetic diversity indices and relatedness computed for the Holothuria scabra populations sampled.

Parameters calculated include the effective population size by the linkage disequilibrium method (NeLD; 95% confidence intervals indicated within brackets), mean number of alleles per locus (A), standardised private allelic richness (Ap, MAF ≥5%): The total number of loci with private alleles detected per population is shown in bold, effective number of alleles (Neff), number of locally common alleles (MAF ≥5%) found in Ho), average expected heterozygosity corrected for population sample size (Hn.b.), inbreeding coefficients (Fis) and average individual multi-locus heterozygosity (MLH). All computations were generated using a dataset containing 6,896 genome-wide SNPs.
