DESIGN AND METHODS: To clarify the clinicopathological characteristics of this malignancy, we analyzed 27 cases of cytogenetically proven dual-hit lymphoma/leukemia.

Among the fish which were cytogenetically studied, most of them do not possess any morphologically differentiated sex chromosomes. On the other hand, karyotypic analysis, chromosome binding, synaptonemal complex observation and comparative genomic hybridization show in few fish species, that there exist sex chromosomes which differentiated at different levels and types.

在进行过细胞遗传学研究的鱼类中，绝大部分没有发现异形性染色体，然而通过核型分析、染色体显带、联会复合体观察和比较基因组杂交等方法，发现在少部分鱼类中确实存在有异形分化的性染色体，并且分化程度高低不等，性别决定方式多种多样。
