Witrynathis is an important fact (Ingman et al., 2003; Ukhee et al., 2005). There is more sequence divergence in mitochondrial than in nuclear DNA (Brown et al., 1993; Giulietta et al., 2000). This may be caused by a faster mutation rate in mtDNA that may result from a lack of repair mechanisms. Sequencing of highly polymorphic
