Full Sibling to Sibling testing. $795 for 2 siblings
and up to 2 parents ($175 for each extra person)
This
test investigates a high number of DNA regions. Full
or half siblings will differ in the amount of DNA that
they share. A Full Sibling to Sibling test looks at
so many pieces of your DNA that we can make an assesment
of your relationship. For example, full siblings will
have DNA matching EXACTLY between them in 40% of regions
tests, whereas non related persons have DNA matching
EXACTLY in around 10% of regions tested.
To
have the Mother's DNA sample (from both or either sibling)
drastically improves the accuracy of
the test.
