Y Chromosome Test (Male Specific)

Special DNA Tests - Chromosome Test through Y chromosome Analysis

Y-STR , or Y Chromosome Short Tandem Repeats, is another testing method we offer. Y-STRs are found only on the male- specific, Y chromosome. This Y chromosome is inherited through the paternal line and is relatively unchanged through many generations. By examining specific locations on the Y chromosome, we can generate a Y-STR profile for each male tested. Males who are related through their fathers will tend to have the same or similar Y-STR profiles, and males who are not related will likely have different Y-STR profiles.

Areas of use in Y-chromosome testing:

When an alleged father is not available for testing, male relatives of the alleged father can be used as a reference; only male children can be tested via this method.

When a mother is not available for testing, the Y-STR method can be used in conjuction with nuclear DNA-STR testing to prove paternity (i.e., mutation cases).

In forensic cases when a mixture is present, where either

	More than one male may be present, it can be used to determine the number of males present
	A male and female mixture is present, the male sample can be masked due to the high concentration of female sample. The Y-STR method will ignore the female portion of the mixture, and only focus on the male sample.

If there is a missing male person, male relatives can be used as a reference to provide a DNA match.

What does a Y-STR chromosome match mean?

	Two individuals that share the same Y-STR haplotype could be related through the same paternal line.
	If individual A has a Y-STR haplotype that matches the Y-STR profile found in an unknown sample, then individual A cannot be excluded as being the donor to that unknown sample. In addition, all patrilineal relatives of individual A cannot be excluded. It may also be true that an unknown number of unrelated males may not be excluded as being the donor of that unknown sample.

There are many scenarios in which the Y-STR test may be used. To determine if this test will be helpful in your particular situation, please contact us or call 800-DNA-EXAM. One of our case consultants will review your particular situation and guide you through the testing process.
