These deviations could be explained by an excess of homozygotes due to population substructure (Wahlund effect within the communities) or by a high inbreeding rate due to widespread endogamy (13,14). The combined power of discrimination and power of exclusion for the 5 new ESS STR loci were 0.9999991 and 0.9954757, respectively. thank you in advance for your time and help.
