mtDNA sequencing
Next-generation sequencing (NGS) is capable of transforming mitochondrial DNA (mtDNA) analysis results. That is, mtDNA analysis enables coroners and forensic laboratories to extract genetic data from a small number of non-ideal forensic samples.
Thousands of copies of mtDNA are carried in every cell in the human body, but copies from different tissues may not be identical. These mitochondrial DNA mutations, called heterogeneity, make it difficult to confirm the sample correlation required for forensic investigations.
