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。
