How is mitochondrial DNA used in forensic science?
Mitochondrial DNA typing is a method used by forensics scientists to match DNA from an unknown sample to a sample collected at a crime scene. It is ideally used in special cases where the DNA is degraded or the source of the sample doesn’t contain enough genomic nuclear DNA for analysis.
Why is mitochondrial DNA so useful?
In anthropological genetics, mtDNA is useful to trace geographic distribution of genetic variation, for the investigation of expansions, migrations and other pattern of gene flow. mtDNA is widely applicated in forensic science. It is a powerful implement to identify human remains.

What is mitochondrial DNA quizlet?
Mitochondrial DNA, found in the mitochondria. mtDNA is totally separate from nuclear DNA in chromosomes. … mtDNA does not recombine during meiosis. The process of recombination in nuclear DNA mixes sections of DNA from the mother and father, creating a garbled genetic history.
Which best describes the mitochondrial DNA?
Mitochondrial DNA is the small circular chromosome found inside mitochondria, which is often called as power house of a sperm cell. Mitochondrial DNA are passed only from mother to offspring through the egg cell.
What was one of the first tests used in forensic science to analyze DNA?
