Consanguinity and its impact on forensic evaluation of traces.

Evolution and culture can have impact on the genetic characteristics of a population and affects the frequency of different variables of a particular genetic make-up. These proportions produce immediate impact on the usefulness of forensic DNA evidence. By examining the genetic population sub-structure within populations and knowing the allele frequency distribution is important to evaluate the expediency of forensic DNA Technology. The population sub-structure can also affect the pragmatism of the existing knowledge when dealing with the evaluation of the submitted evidence.
