Isolation and characterization of microsatellite markers from the Hypoptychus dybowskii (Pisces,Gasterosteiformes)

Hypoptychus dybowskii (Gasterosteiformes) exhibits allopaternal care frequently caused by various types of male reproductive tactics (sneaking, egg desertion and taking over). In order to understand this interesting reproductive system, we isolated microsatellites loci from H. dybowskii. Five microsatellites showed 2–10 alleles and expected heterozygosities ranged from 0.15 to 0.84. These were not significant deviations from Hardy–Weinberg expectations. These results suggest that these novel polymorphic loci should be useful for parentage analysis of H. dybowskii.
