Evidence for paternal DNA transmission to gynogenetic grass carp.

ABSTRACT:

Background

Grass 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.

Result

In this study, ultraviolet-treated sperm of koi carp (Cyprinus carpio haematopterus, KOC, 2n = 100), was used to activate the eggs of GC (2n = 48). Afterwards, cold shock (0-4 °C) was administered for 12 min to double the chromosomes, resulting in GGC. No significant difference (p > 0.05) was found between GGC and GC in appearance, e
