What is Y-STR Analysis?
Y-STR Analysis used the same scientific foundation as STR Analysis, but the DNA fragments that are being targeted in this type of testing are found only on the Y-chromosome making this analysis specific to males only.
This type of DNA testing can be invaluable in cases where male DNA is present on evidence but cannot be detected using traditional STR testing methods.
A Y-STR profile may provide the evidentiary lead needed to supplement an investigation. Although the Y-STR technology can be a powerful tool, please keep in mind the power of discrimination between related persons is greatly reduced since it is likely that male relatives will share the same Y-STR profile.
