Thank you for the Question!

 

Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine another condition. DNA fingerprinting or profiling is a molecular genetic method that is used for the identification of individuals using hair, blood, or other biological fluids or samples. This method is accomplished due to unique patterns (polymorphisms) in their DNA. It is also known as genetic fingerprinting, DNA typing, and DNA profiling.

When sample for individual patterns tested for DNA or suspected sample then a comparisons test used to determine whether they match or not. This method or test is used to distinguish alleles. Some DNA typing methods involve small collections of alleles that can be perfectly distinguished from one another—e.g., a two-allele RFLP system based on a polymorphism at a single locus. Different DNA fingerprinting methods can be used either restriction fragment length polymorphism (RFLP), polymerase chain reaction (PCR), or both, STRs (short tandem repeats), Mitochondrial DNA (mtDNA) testing, forensic DNA typing and Autosomal DNA (atDNA) testing for the DNA testing.
