In DNA paternity test, we do not use probes
for it cannot confirm the identity of an individual. Instead, it technically
rule out a parent in DNA paternity test and this is the reason why we can still
obtain results.
A probe is a small piece of DNA that is a match for a
specific part of a single strand of DNA since everyone’s DNA is different. This
strand is cut into different
number of fragments and different lengths. In paternity
test, the length of these fragments are match with the child.
