Introduction
Molecular markers have proved to be valuable tools in the characterization and evaluation of genetic diversity within and between species and populations. Marker systems differ in their information content, which depends on polymorphism. The concept of polymorphism is used to dene genetic variation in a population, which has been extensively studied in recent years by several established scientic disciplines, for example, genetics, ecology, zoology, and microbiology (Mukherjee et al. 2010; Muneer et al. 2011; Rajkumar et al. 2011). Examples are numerous and obvious. For the practical design of molecular genetic studies, a few questions must be considered. How difcult will it be to nd usefully polymorphic loci? How many markers are needed? How polymorphic must each marker be? These questions can be answered by measuring the information content of the markers. There are two measures of the quality or informativeness of a polymorphism as a genetic marker: heterozygosity (H) and polymorphic information content (PIC). Since its rst application by Botstein et al. (1980) PIC has become the most widely applied
