According to the theory of developmental genetics, genes are expressed selectively at different growth stages in a time- and/or space-specific manner. The whole process of genetic control during development cannot be revealed by data collected at one single time-point; the dynamics of gene expression need to be monitored at various developmental periods during ontogeny. Genetic analyses for body weight trait turbot, at different developmental stages, and statistical methods, including additive and dominance effects for quantitative traits. At the same time, the growth curves of six mating combinations of turbot were divided into four, i.e. slow-growing period, fast-growing early period, fast-growing late period and asymptotic growing period, based on the von Bertalanffyvariance components and the proportion of phenotype variance at the different developmental stages. The results showed thatslow-growing period, fast-growing early period and fast-growing late period of the six mating combinationsslow-growing period, new net additive/he components to phenotype variance of net dominant significantly different. In the fast-growing early period, net additive/significant differencesproportions of net additive/dominant significantly differentfast-growing late period, net additive/dominant were proportions of net additive/dominant significantly different.
