4. DNA fingerprinting is a procedure
used to analyse a person’s unique
collection of DNA fragments.
Ex: Dna from tissue of
hair,saliva,blood or semen found at
the scene can be compared to those
of a suspect.

6. DNA fingerprinting is more accurate than fingerprinting
in the identification of individuals.
DNA fingerprinting is more useful forensic tool than
blood types because many people belong to the same blood
type
It provides more information on a criminal’s identity as it
is more specific.
Very small quantities of DNA are required to carry out a
highly accurate test. Example : small amounts of dried
blood or semen are sufficient to identify the owner.
DNA sample last much longer than fingerprints. DNA
samples that are very old (up to 25 million years) can still be
used.
To test compatibility of potential organ donors with
patients
DNA evidence is much harder to clean up at a crime
scene than evidence such as fingerprints
7. In agriculture DNA fingerprinting is used to know if a
seed is really from the variety being claimed.
Detect genetically modified organisms in agriculture.
Useful in herbal origin authentication, and for the
various claims of medical uses related to some of these
plants.
Identify and breed thoroughbred horses

16. Seen as an infringement of civil liberties especially when
DNA profiles are stored from people who have nothing to
do with a particular criminal offence.
Concerns that the finding of trace amounts of DNA can
falsely implicate a person in a criminal investigation.
Concerns that the complexity of testing and data storage
means errors could occur.
DNA profiles could be related to certain illnesses and
charcter traits and this information would be used by
insurance companies and other organisations to the
disadvantage of the individual.
There is also 1 in 50 billion chance of two DNA sequence
being similar.
