Nucleocytoplasmic Incompatibility in Androgenetic Fish Hybrids Can Be Overcome

Nucleocytoplasmic Incompatibility in Androgenetic Fish Hybrids Can Be Overcome Many androgenetic fish hybrids are nonviable due to the disturbed interaction between the foreign nucleus and the cytoplasm. It has been proposed that this incompatibility can be overcome if eggs from interspecific hybrids and sperm from one of the parental species are used for diploid androgenesis. Indeed, the androgenetic progeny obtained as a result of the insemination of the enucleated eggs of goldfish and carp hybrids by the carp spermatozoa proved to be viable and fertile. This approach may be used for reconstitution of the genotypes of rare or disappearing fish species with the help of induced androgenesis, if their native or cryoconserved sperm is available. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Developmental Biology Springer Journals

Abstract

Many androgenetic fish hybrids are nonviable due to the disturbed interaction between the foreign nucleus and the cytoplasm. It has been proposed that this incompatibility can be overcome if eggs from interspecific hybrids and sperm from one of the parental species are used for diploid androgenesis. Indeed, the androgenetic progeny obtained as a result of the insemination of the enucleated eggs of goldfish and carp hybrids by the carp spermatozoa proved to be viable and fertile. This approach may be used for reconstitution of the genotypes of rare or disappearing fish species with the help of induced androgenesis, if their native or cryoconserved sperm is available.
