Revised G-, Q- and R-banded karyotypes and ideograms for sheep chromosomes
at the 420-band level of resolution are presented. The positions of landmar
k bands on the sheep chromosomes are defined by their distance relative to
the centromere to facilitate comparison with equivalent cattle chromosomes.
Chromosome-specific (reference) molecular markers that have been mapped to
sheep chromosomes and their equivalent cattle chromosomes are proposed. Re
ference markers will facilitate genome comparisons between sheep and cattle
and minimise confusion due to chromosome nomenclature. Numbering of the Ro
bertsonian translocation chromosomes remains as previously reported. Copyri
