  1. The parameters calculated include the effective population size by the linkage disequilibrium method (N eLD ; 95% confidence intervals indicated within brackets), mean number of alleles per locus (A), rare allelic richness at (Ar, MAF <5%), observed heterozygosity (H o), average expected heterozygosity corrected for population sample size (H n.b.), inbreeding coefficient (F is), average individual multi-locus heterozygosity (Av. MLH), homozygosity by locus (HL), standardised heterozygosity (SH) and internal relatedness (IR)
