What is Y-DNA?

Y chromosome DNA (Y-DNA) is the DNA found on the Y chromosome, the male sex chromosome. We each have 23 pairs of chromosomes: 22 pairs of autosomal chromosomes and two sex chromosomes – the X and Y chromosomes.

Females inherit two X chromosomes (one from each parent), while males inherit one X chromosome (from their mother) and one Y chromosome (from their father). Therefore, only males have Y-DNA, so only males can take this Y-DNA test.  

Y-DNA is passed down strictly from father to son along the direct paternal line. The patrilineal inheritance pattern of Y-DNA means that all males who descended from the same patrilineal ancestral lineage will have the same (or very similar) Y-DNA profile.

Y-DNA testing allows you to trace the ancestry of your direct paternal lineage (your father’s, father’s, father’s… paternal lineage). Using your Y-DNA results, you can find out whether you are linked to any other individual along your direct paternal line; you can search a global database to seek potential long lost paternal line relatives from around the world; and you can find out which ancient Y-DNA Haplogroup you belong to.

Note: Only males have Y-DNA so only males can take the Y-DNA test. Females wishing to trace their paternal lineage must test the Y-DNA of a male relative along their direct paternal line, such as a brother, father, male cousin, uncle, etc.

What is a Y-STR test?

A Y-STR test analyzes markers in the Y chromosome known as STRs or ‘short tandem repeats’. STR markers are short segments of DNA (2-13 nucleotides in length), which are repeated multiple times.

STR analyses measure the exact number of repeat units. The number of repeats differs between individuals, because STRs change frequently. Closely related individuals will have similar Y-STR profiles compared to those that do not belong to the same paternal line.

Methods and analysis of Y-STR testing:

The Y-STR test determines the number of repeats at each marker tested – either 20 (standard), 44 (advanced) or 101 (premium) markers, depending on the requested analysis.

When two individuals take a Y-STR marker test, their STR numbers can be compared to see if there is a match. The confidence with which the Y-STR test can predict a relationship between two individuals increases as more STR markers are tested.

A calculation called “TMRCA” (time to most recent common ancestor) can be performed to estimate how many generations ago the two males likely shared a common paternal ancestor. Comparing more Y-STR markers will provide a higher stringency comparison and a more precise TMRCA calculation.

What do you get when you order a Paternal Ancestry (Y-DNA) test?

You will receive a certificate detailing the number of repeats that your carry at each STR marker tested. You will also be able to access the following complimentary databases to bring your ancestry to the next level

  1. DNA Reunion database - search for long lost relatives on your direct paternal line
  2. Indigenous DNA database - find out which indigenous population is the closest match to your paternal lineage
  3. DNA Haplogroups database - trace the ancient migration of your paternal ancestors to their final ancestral homeland
  4. Famous DNA database - compare your DNA against famous historical figures

What can I do with my Y-DNA results?

Using your Y-DNA results, any two individuals can compare their profiles to see whether they descended from the same paternal line. If the Y-DNA test shows that two individuals have different Y-DNA profiles, it would conclusively prove that they did not descend from the same paternal lineage.

You can use your Y-DNA profile to compare with other individuals in your tree to confirm a positive linkage, verify new linkages, or verify findings from your paper research.

You can also use your Y-DNA markers to search our global database to find potential matches from around the world. You can even choose to receive automatic notifications by email whenever a new match is found.

How many Y-DNA markers should I test? 

The Y-DNA STR test determines the number of repeats at a selection of STR markers on the Y-chromosome. They are sections of DNA that vary in the number of copies of a simple repeat sequence. STRs tend to change more frequently than other sections of DNA.

You can select to analyse just 20 STR markers, 44 markers or 101 markers. The more markers you test, the more stringent your comparisons will be when matching against another individual.

For example, a perfect match with another individual at all 101 markers will be a far stronger match than a match at only 20 markers. If you have a 20 marker match with another individual, comparing more markers will provide further clarification of the relevance of the match and will allow you to see if you continue to match when more markers are compared.

If I test only 20 markers, can I test more markers at a later date?

If you test only 20 STR markers, or only 44 STR markers, you can choose to test the remaining markers at a later date. However, you may be required to collect a new sample for the additional testing.
