Gene expression–relative expression (fold change) of (A) insulin-like growth factor 1 igf-1 (B) alcohol dehydrogenase NADP-B adh (C) pyruvate dehydrogenase subunit E1β₂ in the brain, hepatopancreas, red muscle and white muscle of koi×koi (♀K×♂K) and koi x goldfish (♀K×♂G) hybrids. The data points represent replicate measurements (n=4), and the bars are mean±s.e. Statistical tests were conducted on log transformed values. * indicates a significant difference at P≤0.05, ** indicates a significant difference at P≤0.01, between groups.
