Epigenetics of Livestock Breeding

摘要: The animal breeding act has developed from visual assessment of desirable traits, use complex quantitative genetic tools, models and reproductive technologies to the genomics era is potentially moving toward exploitation epigenomics phenomena. Current schemes only account for part phenotypic variance in traits while elusive portion could be due other factors including epigenetics. Numerous lines evidence have shown that epigenetic marks (DNA methylation, histone modifications, chromatin remodeling, noncoding RNA regulation) profoundly influence livestock growth development, outcomes. Thus, outcome a multilevel interaction between genome, epigenome, environmental factors, as well nongenetic factors. This chapter will present an overview historical development art, It sources variation role production reproduction, potential impact on genetics breeding.
