Parentage identification of Odontobutis potamophlia based on microsatellite DNA markers.

Microsatellite loci were used for parentage identification of Odontobutis potamophila in five full-sib families. The combined exclusion probability of the first (E-1P) and the second parent (E-2P) revealed an obvious increase with the increase of number of microsatellite loci. The combined exclusion probability based on allele frequency suggested that at least eight microsatellite loci were needed for the identification of the 150 individuals from five families supported by the genetic distance analysis of individuals of these families. The double-blind test results indicated that the candidate individuals could find their correct parents through these loci thus eight microsatellite markers can be used for pedigree analysis of O. potamophlia in breeding industry as well as for future selection studies.
