Abstract

Genetic markers in blood have been used for paternity investigation and methods to quantify the genetic data into a paternity index or a probability of paternity have been described (1,2,3,4,5). We report here a case where the genetic investigation was attempted to determine whether two adults were biological siblings. A method to quantitate the genetic data and calculate a fraternity index using logic similar to that used to calculate a paternity index was devised for this particular situation. We also report a general method to calculate a fraternity index for a biallelic codominant genetic system.
