3 . Personal Identification : The concept of using DNA fingerprints as a sort of genetic bar code to pinpoint individuals has already been discussed above.

4. Diagnosis of Inherited Disorders: It is also useful in diagnosing inherited disorders in both prenatal and newborn babies. These disorders may include cystic fibrosis, hemophilia, Huntington's disease, familial Alzheimer's, sickle cell anemia, thalassemia, and many others.

5. Development of Cures for Inherited Disorders: By studying the DNA fingerprints of relatives who have a history of some particular disorde, DNA prototypes associated with the disease can be ascertained. The Hong Kong Baptist University was able to use DNA Fingerprinting to identify the Chinese medicine−Lingzhi in 2000.

6 . Detection of AIDS: By comparing the band of HIV "RNA" (converted to DNA using RT-PCR) with the bands form by the man's blood, person suffering with AIDS can be identified.

7. Breeding Program: Breeders conventionally use the phenotype to evaluate the genotype of a plant or an animal. For example, homozygous dominant genotype AABB is always desirable. As it is difficult to make out homozygous or heterozygous dominance from appearance , the DNA Fingerprinting allows a fastidious and precise determination of genotype. Offspring from the discerning mating of superior animals are expected to inherit desirable characters like strong cardiopulmonary capacity and speed. It is basically useful in breeding race horses and hunting dogs.
