DNA Fingerprinting:

DNA Fingerprinting: The DNA of every individual is different. Loci where the human genome differs from individual to individual are called polymorphisms . Polymorphisms may be different alleles of a gene (different base-pair sequences), such as the ABO human blood group multiple alleles.
