| Research Abstract |
To resolve a mechanism that maintains intra-population polymorphism is directly linked to maintenance of genetic diversity, and is important in evolutionary biology and physiology. I have been studying the mechanism for maintaining polymorphism using a group of cichlid fish that exhibit male color dimorphism.
In this study, I conducted linkage-analysis using a rearing population and association study using a wild population, and found that the gene responsible for the dimorphism is located on a genome region that experiences reduced recombination.
I failed to resolve the ecological mechanism for maintaining the dimorphism. I had a hypothesis that the dimorphism was maintained by disassortative mating, but I didn't find any positive evidence for this hypothesis. Instead, I proposed a new hypothesis, it will be tested in the future.
