Compared the similarity and difference of distribution of homologous fragments on X and Y, we suggested that the sex chromosomes of spiny eel have evolved from a pair of homologous ancestral chromosomes, and during the evolution, a pericentric inversion might have occurred on the original Y chromosome, and subsequently terminal regional duplication might have followed, eventually resulting in the differentiation and formation of X and Y chromosomes, then the recombinants between sex chromosomes were repressed, so the sex chromosomes could be inherited steadily.

根据X、Y染色体上同源片段的分布的相似和相异，我们对刺鳅性染色体的分化历程进行了推测，即：刺鳅的性染色体起源于一对原始的同源染色体，通过原Y染色体上的一个明显的臂间倒位，以及染色体末端的异染色质成分的扩增，导致原始Y染色体与X染色体在染色体结构上的分化，从而抑制了X、Y性染色体之间的遗传物质的重组交换，为性染色体的稳定遗传奠定了基础。
