Its chromosome number was estimated at 2n = 48; which consisted of 8 submetacentric and 40 telocentric chromosomes. The karyotype formula was described as 8 sm + 40 t with 56 fundamental arms.

计算其染色体数，结果为2n＝48，其中8条为近中央中结染色体及40条为端点中结染色体，核型公式为8 sm+40 t，染色体总臂数为56。

The karyotype pattern showed that the chromosome number of 2n = 48 contained two metacentric chromosomes, two submetacentric chromosomes, 44 telocentric chromosomes. The karyotype formula is 2 m + 2 st + 44 t and the fundamental number is 52. We will continue to make the karyotype analysis of other tunas in the future.

The analysis of these data shows that in the process of evolution the X chromosomes are as conservative as those in other mammals and the intraspecific and interspecific changes of autosomes follow such a rule:the increase of one chromosome in 2n number is always accompanied by the increase of two acrocentrics and the decrease of one metacentric or submetacentric,and vice versa.

对这些材料所进行的分析表明，鹿属动物在进化过程中，X染色体是很保守的，而常染色体的变化，无论是种间还是种内，全是2n数每增加1条，中部或亚中部着丝点染色体数就减少1条，而端着丝点染色体数就增加2条，反之亦然。

The chromosome number is 2n=96, belonging to hexaploid species (2n=6x=96), and the morphological difference is not obvious among the 96 chromosomes. All the chromosomes are metacentric and submetacentric. Relative length ratio of the longest to the shortest chromosomes is 2.10. There is no satellite chromosome in all the 96 chromosomes. The karyotype formula is 2n=96=60m+36sm, the karyotype type is 2B, a higher karyotype evolution.
