Look further back in time with mtDNA test and Y-Chromosome DNA testing?

Autosomal DNA testing is usually the basic DNA testing that scientists use to determine the ancestry of an individual. But did you know that there are two more categories of DNA testing that you can use for ancestry analysis? Yes, you read that right, you can use the Y-Chromosome DNA testing and mtDNA testing to look further into your ancestry.

Some special features of mtDNA and Y chromosome are:

Both of these elements can are passed on to the next generation with zero to very minimal changes to them. There are many theories behind this phenomenon but here are some of the most popular ones:

In the case of mitochondrial DNA:

There are two reasons why the mtDNA does not change during the recombination process:

Theory no.1-

The main reason for this phenomenon is the absence of mtDNA from the father’s side. The mtDNA from the father side is usually present at the end of the sperm tail to provide energy for movement. But during the fertilization process most of the time only the head enters the ovum.  This loss of tail makes it impossible for the father’s mtDNA to contribute to the fertilization.

Theory no.2-

Another reason for this phenomenon is that the mtDNA contains a total of 37 genes which are all important for normal mitochondrial functioning.

In the case of the Y chromosome:

The only plausible reason why the Y-chromosome does not change is the fact that it does not take part in the standard recombination process.

These facts are what made mtDNA and Y-chromosome DNA testing so powerful. This feature also makes it possible to look back into the ancestral history of an individual. The interesting part is it’s not 3 or 5 generations of ancestors, we are talking about tracing back into hundreds and thousands of generations to the core of your ancestry.
