Computer simulations showed that when no parent information was available, or when information was only available from 1 parent, then exclusion probabilities ranged from 23.6 to 45.1% and from 25.9 to 52.4%, respectively; combined exclusion probabilities for the 8 loci investigated were 97.7 and 98.4%, respectively. However, a breeding experiment with known parental and filial information resulted in 91.28% of progeny being exclusively assigned to their correct parent pair. Our data demonstrate that microsatellite-based parentage assignment is a reliable means with which to obtain information pertaining to genealogical relationships and could therefore benefit genetic conservation of this species.
