利用尼罗罗非鱼和奥利亚罗非鱼种间杂交的F-2后代构建了罗非鱼第二代连锁图谱。该图谱包含525个微卫星标记和21个基因标记。它跨越24个连锁群中的1311 cM，平均标记间距为2.4 cM。我们检测了性别和红色与连锁群3上标记的关联。这张地图将使重要的罗非鱼作为食用鱼的经济文化的数量性状的映射和选择性育种，并将有助于密切相关的慈鲷，经历了爆炸性的适应性辐射在东非湖泊的研究。
We constructed a second-generation linkage map of tilapia from the F-2 progeny of an interspecific cross between Oreochromis niloticus and Oreochromis aureus. The map reported here contains 525 microsatellite and 21 gene-based markers. It spans 1311 cM in 24 linkage groups, for an average marker spacing of 2.4 cM. We detected associations of sex and red color with markers on linkage group 3. This map will enable mapping and selective breeding of quantitative traits important to the economic culture of tilapia as a food fish and will contribute to the study of closely related cichlids that have undergone explosive adaptive radiation in the lakes of East Africa.
