| Outline of Final Research Achievements |
There is individual variation in behaviors of animals, and such variation is called personality. In this study, I investigated using female guppies (Poecilia reticulata) whether the variation in female mate choice is explained by personality or difference of visual system in individuals. As results, the shy females that sensitively reacted for stimulus of predation spent less time for mate choice. On the other hand, the female personality no affected the preference to male, visual sensitivity and type of cone opsin genes. In conclusion, I revealed, in the female guppies, variation of mate preference is not explained by individual personality or visual sensitivity.
