对鲽鱼 (PleuronectesplatessaL.) 和鳕鱼 (Gadus morhuaL.) 的核型分析表明，这两个物种的染色体数量有所不同，但染色体臂数量 (NF) 保持不变。 C、Q 和 R 带模式也证实了所研究的鲽鱼种群表现出罗伯逊多态性。鱼类染色体数目减少的趋势表明罗伯逊融合在鱼类核型进化中发挥作用。
Karyotypic analysis of plaice,Pleuronectes platessaL., and cod,Gadus morhuaL., revealed that the chromosome numbers in both species vary but that chromosome arm numbers (NF) stay constant. The C‐, Q‐ and R‐banding patterns also confirmed that the population of plaice studied shows Robertsonian polymorphism. The tendency of reduction in chromosome number in fishes suggests that Robertsonian fusions play a role in karyotype evolution in fishes.
