(Submitter supplied) Directional selection in the domestication of fish species has resulted in rapid gains of growth, body size, and other production-relevant traits in relatively few generations. While there is clear evidence of genetic divergence contributing to selection-related phenotypic changes, emerging research suggests that intergenerational epigenetic inheritance may also be a relevant mechanism explaining rapid evolutionary change in domestic fish lines. more...

(Submitter supplied) Parental effects represent an important source of variation in offspring phenotypes. Depending on the specific mechanisms involved, parental effects may be caused to different degrees by either the maternal or paternal parent, and these effects may in turn act at different stages of development. In order to detect parental effects acting on gene transcription regulation and length phenotype during ontogeny, the transcriptomic profiles of two reciprocal hybrids from Laval × Rupert and Laval × domestic populations of brook charr were compared at hatching, yolk sac resorption, and 15 weeks after exogenous feeding. more...

(Submitter supplied) The genetic mechanisms underlying hybridization are poorly understood despite their potentially important roles in speciation processes, adaptative evolution, and agronomical innovation. In this study, transcription profiles were compared among three populations of brook charr and their hybrids using microarrays to assess the influence of hybrid origin on modes of transcription regulation inheritance and on the mechanisms underlying growth. more...

(Submitter supplied) Domestication has been practiced for centuries yet directed towards relatively few terrestrial crops and animals. While phenotypic and quantitative genetic changes associated with domestication have been amply documented, little is known about the molecular changes underlying the phenotypic evolution during the process. Here, we have investigated the brook charr (Salvelinus fontinalis) responses to artificial selection by means of transcriptional analysis of ~ 32 000 cDNA features performed in both a selected and control populations reared under identical environmental conditions during four generations. more...
