The formation of the population of the allotetraploid hybrids of red crucian carp and common carp is the first case in the world which both the female and the male of allotetraploids are fertile , they are the good materials for studying the biological characteristic of tetraploid animals , this paper reports the hereditary characters of allotetraploids including the stability of hereditary gynogenesis and androgenesis 异源四倍体鲫鲤是世界上首例人工培育的两性可育的四倍体鱼，这为研究四倍体的生物学特性提供了良好的实验材料，本文对异源四倍体鲫鲤的遗传特性进行了研究，主要包括其遗传稳定性、雌核发育、雄核发育方面的研究。
