We use the most modern
methods to determine paternity. How
does it work?
Every person has two
complete copies of their genetic material, one from their
father’s side and one from their mother’s side. There are
several markers where this information differs from person to
person as you compare their DNA. There are specific markers
within the DNA where you can find repeated sequences. The
number of repetitions is different for every person.
As we analyze the repetitions of these
sequences for enough markers we get either congruity or
differences. If we find only congruities between the alleged
father and the child – we have a very high probability of
paternity. If we find remarkable differences we can exclude
paternity.

We use a highly
efficient method called Polymerasechain reaction. This allows
us to copy and amplify the relevant DNA regions. We then test
for the length and repetitions within the fragments.
Finally a statistical analysis through
modern software allows an exact calculation of the probability
of paternity.
