The Y-STR
paternal lineage test is used to determine whether
two or more males are related through their fathers
(through the paternal/male line). This test is often
used to provide additional evidence in difficult
paternity cases in which the alleged father is not
available for testing. Results of this testing may
also be used to confirm the biological relatives of
an adoptee.

The
Y chromosome is passed from father to son
relatively unchanged through many
generations. The Y-STR test examines
specific locations on the Y chromosome to
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
Although Y-STR analysis cannot distinguish
between males who belong to the same
paternal line, it is useful for excluding
males from an alleged biological
relationship. For example, if a male child
and his alleged uncle (alleged father’s full
brother) are tested, their Y-STR profiles
must match. If they do not, then the alleged
uncle is excluded (not considered a
biological uncle) and the alleged father is
probably not the biological father. |
