DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding .
Modern DNA analysis is based on the statistical calculation of the rarity of the produced profile within a population. While most well known as a tool in forensic investigations, DNA profiling can also be used for non-forensic purposes such as paternity testing and human genealogy research.

Forensic biology is the application of biological principles and techniques in the investigation of criminal and civil cases. [1] [2]Forensic biology is primarily concerned with analyzing biological and serological evidence in order to obtain a DNA profile, which aids law enforcement in the identification of potential suspects or unidentified remains.
An SGM Plus profile retrieved from a DNA database would just list the allele values: [4] 15,18; 6,9; 11,13; 22,22; 31,32.2; 14,17; 17,20; 11,12; 13,16.3; 15,16; XY Each value is the number of tandem repeats within the allele. A non-standard repeat is designated by the number of complete repeat units and the number of base pairs of the partial ...
DNA phenotyping is used when investigators need to narrow the pool of possible individuals or identify unknown remains by learning about the person's ancestry and appearance. When the suspected individual is identified, traditional DNA profiling can be used to prove a match, provided there is a reference sample that can be used for comparison.
As EPIC-seq studies epigenetic markers to infer gene expression, one can study epigenetic sequencing methods like ChIP-seq, [30] ATAC-seq, [31] MeDIP-seq, [32] and Bisulfite-Free DNA Methylation sequencing [33] in combination with methods for profiling RNA expression such as RNA-seq [34] and scRNA-seq.

Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable.
