| Outline of Final Research Achievements |
This study aims at revealing genetic basis of male colour dimorphism of Cyprichromis species, and at revealing mechanism for maintaining the dimorphism.
For the genetic basis, the number of copies of XPO4 gene and SNPs may be associated with the expression of dimorphism. However, we couldn't find genetic mutations that are common between species and couldn't express the dimorphism in transgenic zebrafish. We are preparing for publishing the data we have obtained so far.
For maintenance mechanism, we are testing a hypothesis that male colour morph mating with females differs between seasons. We have sampled two species for a few years and have analysed about half amount of the samples. The results are at present supporting the hypothesis. We have to add more samples to the data before concluding whether this hypothesis is supported.
