Discovery of Two Different Reproductive Development Modes of the Eggs of Artificial Multiple Tetraploid Allogynogenetic Silver Crucian Carp

Abstract

Introduction Artificial multiple tetraploid allogynogenetic silver crucian carp possesses the reproductive function of gynogenesis in spite of incorporating one genome of common carp, because all chromosomes of silver crucian carp are maintained. This was first confirmed in the artificial propagation experiments in which the eggs of the multiple tetraploid fish were respectively inseminated with normal and UV-irradiated sperms of red common carp. Recently,
