Chromosome Doubling in Early Spermatogonia Produces Diploid Spermatozoa in a Natural Clonal Fish1

14 Jan 2009

Abstract excerpt

The natural clonal loach Misgurnus anguillicaudatus (Teleostei: Cobitidae) is diploid (2n = 50) and produces genetically identical unreduced eggs, which develop into diploid individuals without any genetic contribution from sperm. Artificially sex-reversed clones created by the administration of 17alpha-methyltestosterone produce clonal diploid sperm. In metaphase spreads from testicular cells of the sex-reversed...
