| Outline of Final Research Achievements |
Kin relationship was investigated wild Indo-Pacific bottlenose dolphin in Mikura Island, Tokyo, Japan using mitochondrial DNA and 12 microsatellite DNA markers.
As a result of genetic analysis, 2 pairs of dolphins weren't a brother, but it was said that they were a brother by underwater observation. It was suggested that the difference in these results depends on characteristic natural markings on the body wasn't obtained before a offsprings were weaned from their mothers. Moreover, 3 individuals of the paternity dolphin who doesn't participate in offspring rearing was suggested.
It's expected that genetic and kin relationship information becomes basic information like identification information. So, it's necessary to be using with an underwater observation and be doing a genetic analysis to do appropriate maintenance and management.
