The Y chromosome DNA testing is used to know the father-son relationships. This chromosome is transferred the same from father to son. Women have no Y chromosome and hence if any woman wants to do the paternity test then she has to ask her relative to do this test on her behalf.
Y chromosome DNA testing Details
The main benefit of this testing is that you can know all the ancestry records of your father’s side. Ancestry DNA testing can be done by the Y chromosome testing technique. In some cases, where rights have to be taken for a father’s surname then this Y chromosome testing plays an important role. The STR (short tandem repeats) marker on the Y chromosome tells whether two particular individuals are related to each other or not. If the two individuals have the same repeated sequences then they are related to each other. The number of repeated sequences explains the nature of closeness between them.
How the Y chromosome test differs from the mtDNA test
Mitochondrial DNA testing is totally related to the Mother. The main difference between the Y DNA test & mtDNA test is that later testing can’t tell you how much you are related to your mtDNA matches. The other main difference is that the mtDNA test is not considered very useful in genealogy research. The main reason behind this is that women keep changing their surnames. The mtDNA also changes very slowly and can remain the same for dozens of generations.

What is Y-DNA testing?
The human Y chromosome, which is completely and unaltered transferred from dads to children, is examined using Y-DNA testing. Our straight male lineage can be used to confirm common paternal heritage by following markers of the men-specific chromosome. It explores how male ancestral lines are linked together by following with the surname origins. Y chromosome testing offers unique information on your uninterrupted paternal history, enabling ancestral investigation, in contrast to ancestral tests that include every chromosome.
What does mtDNA tell you?
As an illustration, mitochondrial DNA (mtDNA) test kits examine the motherly transmitted nuclear genome. Kids of the same generation inherit mtDNA from their biological mothers, which makes it possible to trace maternal ancestry. However, this gene marker is only passed on to the following generation by females through recombination. Your maternal ancestors’ exploration of the mother parts of your familial lineage is directly linked to your mtDNA links. mtDNA sheds light on ancestry across all-female lineages, whereas Y-DNA maps paternal lineage.

How do Y-DNA and mtDNA testing differ?
Y Chromosome DNA
Acquired from the father
acquired from mothers.
Father-to-son transmission that reveals solely masculine lineage
maintains the maternal female lineage.
The Y chromosomal examination
Testing of the mitochondrial DNA
Investigate male traces that are related
Adheres to ancestral lineages that are exclusively feminine.
not connected to surnames
encourages paternity research
upholds mother-child relationships
To summarise, the use of Y-DNA and mitochondrial testing provides distinct understandings of our mitochondrial and Y chromosome lineages. Even though genetic testing includes every lineage, you may focus on the important straight male and female genes that shape your ancestry using Y-DNA and mtDNA analysis. To learn about your ancestry, the Face DNA Test provides two different kinds of focused testing.
