Outline of Final Research Achievements	To characterize the net-sex chromosomes, we conducted whole genome sequencing of the Japan Sea and Pacific Ocean sticklebacks. We also identified a candidate gene encoding a TRIM gene within the QTL causing hybrid male sterility. To investigate the patterns of sex chromosome-autosome fusions, we made a database and analyzed the patterns. To explain the observed patterns, we proposed that female meiotic drive, genetic drift and sexually antagonistic selection may drive the fusions.
