Sibling DNA Test
In the Sibling DNA Test (sibling
test), two children are tested
to determine whether they share
the same biological parent or
parents. Full siblings are
individuals who have the same
biological mother and the same
biological father. Half siblings
share only one parent. Sibling
DNA Test (sibling test)
determines the likelihood that
two individuals are full or half
brother(s) and/or sister(s).
| Since siblings have the
same parent(s), they
have matching genes much
more often than do two
unrelated individuals.
When matches between two
potential siblings are
found, calculations are
made to determine the
probability that a
sibling relationship
exists.
The Sibling DNA Test
usually shows a number
of genetic matches in
true biological
siblings. In such cases,
the GENETICA DNA Test™
for siblings may show
the probability of
siblingship to be
greater than 99%,
provided the tested
alleged siblings
inherited genes that are
not commonly present in
the population. |

The Sibling DNA Test is often a
useful and informative test when
only two potential siblings are
available for testing. However,
in some cases, testing
additional known family members
(in addition to the two
potential siblings) greatly
improves the accuracy of this
DNA test.
