Table 1 Forensic parameters of the nine Koompassia malaccensis STR loci for the three regional database; West Malaysia (WM), East Malaysia (EM) and Peat Swamp (PS). A: number of alleles; H_o: observed heterozygosity; H_e: expected heterozygosity; PIC: polymorphism information content; HWE: Hardy-Weinberg equilibrium; MP: matching probability; PD: power of discrimination. ^bSignificant departure from Hardy-Weinberg equilibrium after bonferroni correction (P < 0.05/9 = 0.0056).
