Research Abstract |
We determined the whole genome sequence of the Japan Sea and Pacific Ocean female sticklebacks. We searched for rapidly evolving DNA-binding proteins within the hybrid male sterility QTL. By using the comparative genome hybridization, we examined the degeneration of the neo-Y chromosome and dosage compensation. We also found QTL for morphological variation between these two species. We also compiled cases of autosome-sex chromosome fusions and proposed that female meiotic drive contributes to the neo-sex chromosome evolution.
