LAGOS L, Marcela; POGGI M, Helena  y  MELLADO S, Cecilia. Basic concepts about paternity testing. Rev. méd. Chile [online]. 2011, vol.139, n.4, pp.542-547. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872011000400019.

Nowadays, the analysis of genetic markers is a very important and validated tool for the identification of individuals, and for paternity testing. To do so, highly variable regions of the human genome are analyzed, making it possible to obtain the genetic profle of an individual, and to distinguish between different individuals. The methodology used is basically the same all over the world, consisting in the analysis of 13 to 15 markers. To assign biological paternity the child must have inherited the characteristics from the alleged father in each of the genetic markers analyzed. This analysis achieves a certainty higher than with any other test, which is expressed as the probability of paternity. This probability has to be at least 99.9%, but greater probabilities are usually obtained, especially if the mother is included in the analysis. If the characteristics of two or more genetic markers from the alleged father are absent in the child, biological paternity is excluded.
