Previously, perceived competence of and attraction toward targets categorized by race showed in-group bias and no bias, respectively. Consequently, previous investigators regarded intergroup perception as a compromise between the norms of in-group bias and fair-mindedness. An alternative hypothesis for such findings is that attraction is not as relevant a dimension for intergroup discrimination as is competence. To test contrasting predictions of these hypotheses, the present authors asked participants from the majority and minority groups in Singapore (ns = 320) to evaluate either competence of or attraction toward one of the five targets. Consistent with the hypothesis that intergroup perception is a compromise, both dimensions yielded a uniform but weak in-group bias. The participants' equating of the in-group with one out-group further illustrated fair-mindedness. The authors discussed implications of the findings.

Human mitochondrial DNAs (mtDNAs) from 153 independent samples encompassing seven Asian populations were surveyed for sequence variation using the polymerase chain reaction (PCR), restriction endonuclease analysis and oligonucleotide hybridization. All Asian populations were found to share two ancient AluI/DdeI polymorphisms at nps 10394 and 10397 and to be genetically similar indicating that they share a common ancestry. The greatest mtDNA diversity and the highest frequency of mtDNAs with HpaI/HincII morph 1 were observed in the Vietnamese suggesting a Southern Mongoloid origin of Asians. Remnants of the founding populations of Papua New Guinea (PNG) were found in Malaysia, and a marked frequency cline for the COII/tRNA(Lys) intergenic deletion was observed along coastal Asia. Phylogenetic analysis indicates that both insertion and deletion mutations in the COII/tRNA(Lys) region have occurred more than once.

Determining the racial affinity of an unknown individual from dentition for identification is indeed a difficult endeavour. However, there are certain dental characteristics which are predominant in certain racial groups and these contribute important indicators in the identification process. Inherited dental characteristics are modified by prenatal and postnatal environmental and nutritional conditions. They can also become less discernible due to admixture of the various races.
