Aunts & Uncles
When one of the parents is not available for testing, it may be
beneficial to have an avuncular DNA test performed. A comparison can
be made between the aunt/uncle and the child without additional family members,
although, adding the common parent will help clarify the comparison.
What do we share
in common?
Aunts/uncles
will share a quarter of there DNA in common with their niece/nephew
if they are related as a full sibling to the parent in question.
Testing the parent not in question will help eliminate the
contribution from that parent and focus solely on the DNA inherited
from the questioned parent. (see
science of paternity)
All about
Likelihood
Because aunts/uncles
don't have to share alleles in common at each location, the best
possible information that can come from an avuncular comparison is how
likely the two individuals are related vs. unrelated. If the
questionable parent is still
alive and a sample can be obtained, it is strongly recommended that
a sample be collected from him/her for paternity/maternity comparison to the
child.
