A high-resolution radiation hybrid map of bovine chromosome 5q1.3-q2.5 compared with human chromosome 12q.
In this study we present a comprehensive 3000-rad radiation hybrid map on bovine chromosome 5 (BTA5) of a region between 12.8 and 74.0 cM according to the linkage map, which contains a quantitative trait loci for ovulation rate. We mapped 28 gene-associated sequence tagged site markers derived from sequences of bovine BAC clones and 10 microsatellite markers to the BTA5 region. In comparison with HSA12q, four blocks of conserved synteny were apparent showing three chromosomal breakpoints and two inversions in this segment of BTA5. Therefore, we have improved breakpoint resolution in the human-bovine comparative map, which enhances the determination of candidate genes underlying traits of interest mapped to BTA5.
