*About
Y-Chromosome tests:
For
Grandfather to Grandson tests, Y-chromosome testing is your least expensive
option while obtaining very high accuracy (99.9%+). Think about the father
of the child (the son of the Grandfather), if this man is NOT the biological
father of his son, then you need know if there is any possibility that
the true biological father was not a close relative. (ie, could other
possible father be a brother, cousin or other type of close relative to
the alledged father?)
If
the answer is no, then a Y-chromosome test is a great option. All men
have one Y chromosome, it is passed down from Father to Son, woman have
no Y-chromosome DNA. Therefore a Grandfather, his son and his 3 grandsons
will all have the SAME Y-chromosome DNA
*About
X-chromosome tests:
For
Grandmother to Granddaughter tests, X-chromosome testing
is your least expensive option while obtaining very
high accuracy (99.9%+). Think about the father of the
child (the son of the Grandfather), if this man is NOT
the biological father of his son, then you need know
if there is any possibility that the true biological
father was not a close relative. (ie, could other possible
father be a brother, cousin or other type of close relative
to the alleged father?)
If
the answer is no, then a X-chromosome test is a great option. All men
have one X chromosome, it is passed down from Father to Daughter, woman
have two X-chromosomes. Therefore a Grandmother, her son, and her 3 Granddaughters
will all have at least one of their X-chromosomes exactly the same.
