We report the most extensive physically anchored linkage map for cattle produced to date. Three-hundred thirteen genetic markers ordered in 30 linkage groups, anchored to 24 autosomal chromosomes (n = 29), the X and Y chromosomes, four unanchored syntenic groups and two unassigned linkage groups spanning 2464 cM of the bovine genome are summarized. The map also assigns 19 type I loci to specific chromosomes and/or syntenic groups and four cosmid clones containing informative microsatellites to chromosomes 13, 25 and 29 anchoring syntenic groups U11, U7 and U8, respectively. This map provides the skeletal framework prerequisite to development of a comprehensive genetic map for cattle and analysis of economic trait loci (ETL).
我们报告了迄今为止构建的最全面的牛物理锚定连锁图谱。总结了313个遗传标记,它们排列在30个连锁群中,锚定到24条常染色体(n = 29)、X和Y染色体、4个未锚定的同线群以及2个未分配的连锁群,覆盖牛基因组2464厘摩。该图谱还将19个I型基因座定位到特定染色体和/或同线群,并将4个含有信息丰富微卫星的黏粒克隆分别定位到锚定同线群U11、U7和U8的13号、25号和29号染色体上。该图谱为牛综合遗传图谱的开发和经济性状基因座(ETL)分析提供了必要的框架基础。
