In this study, on the basis of information theory and statistical methods, we use mutual information, n-tuple entropy and conditional entropy, combining with biological characteristics, to analyze the long range correlation and short range correlation in human Y chromosome palindromes.

本文中，我们利用信息论和统计学的方法并结合生物学的特征研究人类Y染色体回文序列的互信息、'n字'熵、条件熵，定量分析了回文序列的长程关联和短程关联，发现其中既存在长程关联，也存在短程关联，并且它们主要是由序列中的重复序列引起的。

再以黑麂的Y1，Y2，X+4和1号染色体的DOP-PCR产物为模板，用人的特异性的SRY（sex determining region of the Y chromosome）基因引物对其进行扩增，结果表明黑麂只有Y2染色体出现了SRY扩增片段。
