With compared to other species of schizothoracinae fishes , the diploid chromosome number of qinghai - lake nakked carp was equal to schizothorax waltoni , s . o ' connori , oxygymnocypris stewarti , schizoygopsis pylzovi and chuanchia labioza . this showed that these schizothoracinae fishes which diploid chromosome number were 92 were likely to have experienced similar ecological environment as they involved into special qinghai - tibten plateau - adaptive species gradually 由此反映出具有92条染色体的裂腹鱼在逐渐演化成适应于高原生态环境的特殊类群时，可能经受过相同或相近的生态处境；与大多数裂腹鱼一样，青海湖裸鲤也可能是二倍化了的多倍体；青海湖裸鲤可能是某些原始的?类通过演化和自然选择，逐渐演化成适应于高原生态环境的特殊类群。
