COMPARISON OF HAE-III-GENERATED VNTR PROFILES OF CHINESE IN HONG-KONGAND SINGAPORE

Some statistical analysis and experiments have been carried out on the single-locus VNTR reference databases collected separately from the C hinese in Hong Kong and Singapore to assess the issues of sample size and representativeness in the context of forensic science. We employed the bootstrap method and the Pearson chi-squared test for independenc e, and found that the different reference databases have very little e ffect in assessing the frequencies of occurrence of variable number of tandem repeats (VNTR) profiles. The results of random match probabili ty assessment also indicate that the sample sizes studied appeared ade quate to provide representative data. It has been found that a battery of four loci was enough to distinguish the 458 individuals under stud y.
