Abstract
1 Introduction Gynogenesis is a rare reproductive mode in fish. Among a few of species reproduced by this method, silver crucian carp (Carassius auratus gibelio) is the most special one. The specialities mainly include the following two aspects: (ⅰ)The crucian carp exists as a bisexual population which can be reproduced by natural gynogenesis, because there are both gynogenetic function and certain proportion of males in the offsprings; (ⅱ) heterologous
