Dna
Fingerprint Test on wiseGEEK:
All these items, with their sweat, skin,
mucus, blood, semen, ear wax, and/or saliva offer the possibility of DNA and
the ability to identify a person’s presence and possibly activity at a crime
scene. DNA fingerprinting also has application in paternity testing and
ecological research. In paternity testing, the genotype of child is compared to
mother and alleged father(s).
Except for identical twins, each person has a
unique DNA structure which becomes his genetic fingerprint, yet at the same
time shares a common DNA sequence pattern with other family members.
Information
On Dna Fingerprinting on wiseGEEK:
DNA
fingerprinting has a high success rate and a very low false-positive rate,
making it an extremely popular form of paternity and maternity verification. In
forensics, DNA fingerprinting is very attractive because it doesn't require
actual fingerprints, which may or may not be left behind, and may or may not be
obscured.
If there is a match, or inclusion, then the
DNA fingerprint is compared to appropriate ethnic population database, and the
probability of relationship is calculated and reported. In ecological research,
DNA fingerprinting has helped in identification of extra pair offspring (EPO)
the name given to chicks that have been sired by a male partner other than
their social partner.

kits are kits which contain the materials necessary to identify fingerprints
and to collect them so that they can be used in analysis. Forensic technicians
often carry fingerprint kits in the bags they take to the field, and they are
also kept in law enforcement agencies for the purpose of working in the lab.
