A Tripolar Spindle Formed at Meiosis I Assures the Retention of the Original Ploidy in the Gynogenetic Triploid Crucian Carp, Ginbuna Carassius auratus langsdorfii

1 Dec 1993

Abstract excerpt

A triploid crucian carp, ginbuna (Carassius auratus langsdorfii), reproduces by gynogenesis, in which sperm of diploid ginbuna or of other species triggers the development of the triploid eggs, but a male genome makes no contribution to the zygotic genome. Gynogenesis is maintained by two mechanisms: exclusion of male genome during fertilization and retention of somatic ploidy levels during oogenesis. We examined...
