Fig. 1From: Heterosis of growth trait regulated by DNA methylation and miRNA in allotriploid fishHeterosis of growth traits in the two triploid fish (8Â months after hatching). A The procedure for the two allotriploids (3nR2C and 3nRC2). B The appearance of the two triploids and their inbred parents. The ratio of average body height and body length (H/L) is marked.
