| Outline of Final Research Achievements |
Our phylogenomic analysis revealed that all Japanese freshwater populations are derived from Gasterosteus aculetus rather than Gasterosteus nipponics. We found that differences in the ability to produce an poly unsaturated fatty acids and the copy number of an enzyme explains the different ability to colonize freshwater.
