Do you know how is Mitochondrial DNA mtDNA typing used in forensic science

Mitochondrial typing is a process whereby the DNA of an individual is matched with a DNA sample is found on the crime location.

It is one kind of method that is mainly done at forensic labs to locate the accused with the help of the DNA of the individual. It is called DNA typing.

but Mitochondrial DNA (mtDNA) is also a very effective tool for concluding the geographic origin of populations. MtDNA is gently inherited and doesn’t undergo recombination and its diverse families are structured geographically

About Mitochondrial DNA (mtDNA):

Mitochondrial DNA (mtDNA) is a powerful tool for inferring the geographic origin of populations. MtDNA is maternally inherited, does not undergo recombination and its different lineages are geographically structured in human populations.

The high sensitivity of mtDNA analysis lets forensic scientist get information from old evidence items which are associated with the cold case and small evidence pieces contain little biological material.

Such samples must have the same mtDNA profile as all maternal relatives inherit the similar mtDNA.

If you are wondering do all humans have the same mitochondrial DNA? We must say that there are about 37 genes in mtDNA and they can vary from person to person.

About the properties and applications of Mitochondrial DNA:

In anthropological genetics, mtDNA is valuable to trace the geographic supply of genetic variations. It is widely applied in forensic science. mtDNA is a powerful tool to classify human remains.

How long does Mitochondrial DNA last?

How long does Mitochondrial DNA last

If the body is left in the rain and sun, its DNA can be used for testing for only a few weeks. And it is covered a few feet below the ground, then the DNA will last for about 1,000 to 10,000 years.

Also, it is important to know that if it is frozen in Antarctic ice, it could only last a few hundred thousand years.
