They include the variation of the degradement velocity of different sample, the inhibition product of PCR, the amount of DNA extraction, quality of DNA and the heteroplasmy of some tissue. Correct sequencing, comparison of the result of forward and reverse primers sequencing should be done to rule out wrong signals, and prevent contamination. In addition to gene sequencing, low grade heteroplasmy could be dealt by Denaturing high performance liquid chromatography. Multiplex Ligation-dependent Probe Amplification. The analysis of mitochondrial HV Ⅰ, HV Ⅱ sequencing is able to identify the maternal sanguinity, then it could assist in the human identification. It also complements the genomic STR system in distribution of population, the origin of human, and analysis for fossil.
