Pricing and turnaround time
Y chromosome testing is priced at £199 for two males to be tested with results ready in only 5-7 working days.
A Y chromosome test to establish paternity
The Y chromosome test can be used to confirm paternal relationship whenever a direct male line can be drawn between the participants.
Any male individuals that share the same paternal line will share the same Y chromosome. This means that paternal grandfather, father and son will all share a carbon copy of their Y chromosome. In cases where an alleged father is not available and you are unable to carry out a home paternity test by directly comparing the DNA of the alleged father and son, we would recommend testing two paternal relatives in a Y chromosome test. If the tested males have the same Y chromosome profile, we can conclude that they also share the same paternal line.
Other uses of Y chromosome testing
The test may also be done when two first cousins wish to determine in a scientifically reliable way whether their fathers were in fact brothers, or to check if their grandfather is common to both. In such cases this may be determined by doing a Y-STR test.
It is important to understand that this type of test may not always be able to determine the exact relationship between tested males. The result therefore needs to be interpreted within the context of the case.
How accurate is the test?
The Y chromosome has a very low rate of mutation and therefore, it provides a reliable means of testing for biological relationships between males. The test will show the Y-STR profile for each male tested.
Establishing ancient paternal ancestry
The Y chromosome is such a strong marker of male ancestry that any male can trace his ancient paternal lineage by testing their Y chromosome. Another test we offer that also looks at the Y chromosome is that paternal lineage test; this is a deep ancestry test that is able to trace the roots of one’s paternal ancestry many thousands of years back taking them right back to their very earliest forefathers.
