Abstract

The evolutionary dynamics of a highly conserved microsatellite locus (Dla 11) were studied in several fish species. The data indicated that multiple types of compound microsatellites arose through point mutations that were sometimes followed by expansion of the derived motif. Furthermore, extensive length variation was detected among species in the regions immediately flanking the repeat region.

摘要

研究了多个鱼类物种中高度保守的微卫星位点（Dla 11）的进化动态。数据表明，多种类型的复合微卫星是通过点突变产生的，有时伴随着衍生模体的扩展。此外，在重复区域附近的区域中，在物种之间检测到广泛的长度变异。
