Abstract
The extent and distribution of conserved chromosomal segments between pig and cattle chromosomes were established using hybridization of porcine chromosome painting probes on bovine metaphases. A total of 44 segments of conserved synteny were identified, resulting in a nearly complete coverage of the bovine karyotype. This study provides new data on chromosome evolution of mammals.
摘要
利用猪染色体涂染探针与牛中期染色体杂交，确定了猪和牛染色体之间保守染色体片段的范围和分布。共鉴定出44个保守同线片段，几乎覆盖了牛的核型。本研究提供了关于哺乳动物染色体进化的新数据。
