Evidence for paternal DNA transmission to gynogenetic grass carp

摘要

BackgroundGrass carp (Ctenopharyngodon idellus, GC), as the highest-output fish in China, is economically important. The production of gynogenetic grass carp (GGC) will provide important germplasm resource for producing improved GC. At present, knowledge regarding the heterologous sperm DNA in gynogenetic offspring is little. Thus, revealing paternal DNA in GGC at the molecular level would be highly significant for fish genetic breeding.
