The developmental phenotype system of gynogenetic haploid goldfish embryo is a suitable analytic system for investigations on genomic regulatory mechanisms and general principles of genes selective expression pattern at the whole genome level.

Studies on artificial induction of haploid gynogenesis in oyster Crassostrea hongkongensis;

The early embryonic development and the cytological observation of gynogenesis in sea urchin Hemicentrotus pulcherrimus artificially induced;

Identification of F_1 progeny of gynogenesis in common carp by RAPD analysis;

To analyse hereditary features and and rules of the foreign gene in the trans-Hu-IFN-α-gene carp,PCR testing technology were employed to test the Hu-IFN-α gene’s genetic expression in its cross F1 and gynogenesis F1 generation.

The paper deals with growth comparison between different strains of gynogenetic silver carp and common silver carp at age 1 under the same culture condition in ponds.
