Summary The regional localization of five reference loci to sheep chromosomes is reported. The newly mapped loci are the T‐cell receptor, beta ( TCRB ), coagulation factor X ( F10 ), laminin gamma 1 ( LAMC1 ), cyclic GMP rod phosphodiesterase, alpha ( PDEA ) and fibroblast growth factor 2 ( FGF2 ). The assignments of PDEA and LAMC1 to chromosomes 5q23–q31 and 12q22–q24 respectively provide the first markers physically assigned to these chromosomes. They also allow the provisional assignment of sheep syntenic group U19 to chromosome 5 and U1 to chromosome 12. The mapping of FGF2 to chromosome 17q23–q25 anchors the unassigned linkage group ‘A’ to chromosome 17, and the assignment of TCRB to chromosome 4q32–qter facilitates the orientation of a linkage group on sheep chromosome 4. The mapping of F10 to sheep chromosome 10q23–qter supports the recent assignment of bovine syntenic group U27 to cattle chromosome 12, as sheep chromosome 10 and cattle chromosome 12 are banded homologues.
