Reversed abnormality is one of the common deformities in flat fish species. To identify the cause of reversed abnormality in Japanese flounder from a hatchery population, we evaluated genetic variability and parentages in reversed individuals using microsatellite DNA markers. Seventeen parents were used for the seed production, and 52 normal and 49 reversed individuals were sampled at 96 day-post-hatched. There were no differences in heterozygosity and allele frequencies between normal and reversed individuals. The parentages of all specimens used in this study were identified by microsatellite DNA data. Parentage analysis indicated that normal individuals were generated from 7 female and 5 male parents, and 14 parental pairs were observed. Reversed individuals were generated by 7 female and 7 male parents, and 18 parental pairs were observed. One female parent significantly generated a higher rate of reversed individuals compared to the other female parents. These results support the fact that reversed individuals identified in a hatchery population had arisen via environmental effects, although some were due to genetic and/or maternal effects.
