| Research Abstract |
This study aimed at locating genomic regions which determines species specific body size in fish. We used second generation hybrid (F_2) and backcross (BC) between Takifugu rubripes (fugu) and T. niphobles (kusa-fugu) to conduct QTL analysis for growth rate. In the first year, we locate a QTL harboring 1.5Mbp on a single linkage group of fugu. We introduced a fugu BAC, included the region with highest LOD score, into T. niphobles by microinjection. These injected individuals are to be used to examine the effects of genes included in the BAC.
