Intraspecific polymorphism with regard to autosomes has been observed in Cassida syrtica, where an additional large autosome (marker chromosome) has been encountered in the diploid as well as the haploid set of chromosomes. The diploid number for the normal type is 18 (n = 8 + Xyp). Its polymorphic form reveals a diploid set of ninetten chromosomes with an exceptional karyotype (n = 8 + 1 Mt + Xyp).
在叙利亚卡西达叶甲中观察到了关于常染色体的种内多态性，在其二倍体和单倍体染色体组中都发现了一条额外的大型常染色体（标记染色体）。正常类型的二倍体数目为18（n = 8 + Xyp）。其多态形式显示出具有异常核型（n = 8 + 1 Mt + Xyp）的19条染色体的二倍体组。
