Induced Androgenesis in Fish: Obtaining Viable Nucleocytoplasmic Hybrids

Induced Androgenesis in Fish: Obtaining Viable Nucleocytoplasmic Hybrids A self-review of long-standing studies of induced androgenesis in fish. The data are provided on the induction of diploid androgenesis in teleost fish via blocking the first cleavage division and the development of the method of dispermic androgenesis in sturgeon fishes. Androgenetic nucleocytoplasmic hybrids were obtained using the method of dispermic androgenesis and eggs of previously produced true interspecific hybrids. Specific morphological features of androgenetic hybrids were described and dispermic androgenesis was realized using cryopreserved sperm. The mechanism of sex determination in sturgeon fishes is discussed with reference to possible use of androgenesis for restoration of rare and disappearing species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Developmental Biology Springer Journals

Abstract

A self-review of long-standing studies of induced androgenesis in fish. The data are provided on the induction of diploid androgenesis in teleost fish via blocking the first cleavage division and the development of the method of dispermic androgenesis in sturgeon fishes. Androgenetic nucleocytoplasmic hybrids were obtained using the method of dispermic androgenesis and eggs of previously produced true interspecific hybrids. Specific morphological features of androgenetic hybrids were described and dispermic androgenesis was realized using cryopreserved sperm. The mechanism of sex determination in sturgeon fishes is discussed with reference to possible use of androgenesis for restoration of rare and disappearing species.
