| Outline of Final Research Achievements |
A novel wild - derived heterogeneous stock (WHS) was established by genetically mixing with eight wild strains. We conducted selective breeding for active tameness to humans and selected and non - selected groups were successfully established. By conducting SNP analysis using genomic DNA on these selected and non-selected groups of mice, we performed genetic analysis for active tameness. We found genetic loci relating to active tameness on chromosome 11. In order to narrowing down the loci, we conducted comparative analysis of mouse and dog genome. We found that the data of the selected region showed high degree of overlap with the genomic regions which were selected during the evolution of dog breeds.
