[A population genetic study of 22 autosomal loci of single nucleotide polymorphisms].

Objective: To evaluate polymorphisms and forensic efficiency of 22 non-binary single nucleotide polymorphism (SNP) loci.

Methods: One hundred ethnic Han Chinese individuals were recruited from Dongguan, Guangdong. The 22 loci were genotyped with matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS).

Assessing forensic applications of the frontal sinus in a Chinese Han population.

The frontal sinus is an important tool of personal identification. To assess the forensic applications of the frontal sinus patterns in a Chinese Han population, 198 individuals were analyzed. 165 individuals who have the frontal sinus were observed in this population, and 12 parameters of the frontal sinus were observed according to Yoshino's method.
