Abstract
A bay roan Brabant Belgian stallion (ERnl ern) was bred to eight chestnut Ameiican Belgian mares (eml ern), producting 57 foals. Thirty foals were bay roan, 25 were chestnut, one was bay, and one was chestnut roan. The recombination rate was 0.035 ± 0.024, Indicating fairly close linkage between the roan (Rn) and extension (E) loci.
