| Outline of Final Research Achievements |
Guppies maintain a significant diversity in male body colorS and in female mate preference for male body color. In this study, we aimed to identify the genomic regions of males selected by pre- and post-mating female preferences in the field populations. The analysis detected 402 ~ 434 candidate genes in each population. Among the candidate genes, several genes related to signal traits (body color and fins) and viability (immunity and antioxidation) were detected. Immune and antioxidant genes may be good genes for improving survival in offspring. This study could obtain the candidate genes which might be related to the evolution of mate preference of the female.
