How is mitochondrial dna (mtdna) typing used in forensic science?

THIS IS THE BEST ANSWER 👇

Mitochondrial DNA typing (mtDNA) is used in forensic science because it is an important tool for the sample source of damaged DNA, degradation or recovery. Mitochondrial DNA is a small genome found in the mitochondria, just outside the nucleus of the cell. Hair, bones, and teeth are usually the most common samples examined for mtDNA.
