性染色体和常染色体之间的易位产生了多个性染色体系统。这是意想不到的，因此，进化的意义并不清楚。目前的研究显示，台湾棕蛙(Odorrana Swinhoana)的多性染色体系统由三对不同的染色体组成。男性特有的三个易位创造了一个由六条性染色体组成的系统，♂X1Y1X2Y2X3Y3-♀X1X1X2X2X3X3。它的独特之处在于，易位发生在潜在的性别决定染色体的六个成员中的三个，已知这些染色体与青蛙的性染色体周转有关，三个成员中的两个包括哺乳动物、鸟类和鱼类的性别决定基因的同源基因。这种罕见的病例提示了性别特异性的非随机易位，从而为多性染色体系统的进化意义提供了一个新的观点。
Translocation between sex-chromosomes and autosomes generates multiple sex-chromosome systems. It happens unexpectedly, and therefore, the evolutionary meaning is not clear. The current study shows a multiple sex chromosome system comprising three different chromosome pairs in a Taiwanese brown frog (Odorrana swinhoana). The male-specific three translocations created a system of six sex-chromosomes, ♂X1Y1X2Y2X3Y3-♀X1X1X2X2X3X3. It is unique in that the translocations occurred among three out of the six members of potential sex-determining chromosomes, which are known to be involved in sex-chromosome turnover in frogs, and the two out of three include orthologs of the sex-determining genes in mammals, birds and fishes. This rare case suggests sex-specific, nonrandom translocations and thus provides a new viewpoint for the evolutionary meaning of the multiple sex chromosome system.
