The basic diploid number of chromosomes in the family Cobitidae was deemed to 2n=50. The C . sinensis with 2n=40 may originate from the ancestor of the subfamily Cobitidae. The C sinensis with 2n=90 which reserved all of 40 original chromosomes maybe result from heterologous hybridization among some fishes of the subfamily Cobitidae. The C . sinensis with 2n=76 is probably a branch of hybrid offspring.

鳅科鱼类染色体的祖先二倍数是2n=50，2n=40的中华花鳅可能是由类似于泥鳅的2n=50的鳅亚科祖先经罗伯逊易位2n=50→48→40转变而来的。2n=90的中华花鳅保留了初始的40条染色体，它可能是由2n=40的中华花鳅与同为鳅亚科的其它鱼类杂交后演化而来的。2n=76的中华花鳅并非异源三倍体，它可能是杂交后演化的一个分支。
