Abstract

Partial genetic linkage maps, based on microsatellite markers, were constructed for two tilapia species, Oreochromis aureus and Oreochromis niloticus using an interspecific backcross population. The linkage map for O. aureus comprised 28 markers on 10 linkage groups and covered 212.8 CM. Nine markers were mapped to four linkage groups on an O. niloticus female linkage map covering 40.6 CM. Results revealed a high degree of conservation of synteny between the linkage groups defined in O. aureus and the previously published genetic linkage map of O. niloticus.

摘要

利用种间回交群体，基于微卫星标记构建了两种罗非鱼（奥利亚罗非鱼和尼罗罗非鱼）的部分遗传连锁图谱。奥利亚罗非鱼的连锁图谱由10个连锁群上的28个标记组成，覆盖212.8厘摩。9个标记被定位到尼罗罗非鱼雌性连锁图谱的4个连锁群上，覆盖40.6厘摩。结果显示，奥利亚罗非鱼中定义的连锁群与先前发表的尼罗罗非鱼遗传连锁图谱之间存在高度的同线性保守性。
