Mean predicted proportions, using each of the methods studied, for Romney (pRom), Coopworth (pCoop), Perendale (pPere) and Texel (pTex) in animals that are purebred (recorded as 100% of a particular breed; breeds with at least four animals available shown) and not used in the genomic selection training set. Proportions where the breed being predicted is the same as the recorded breed are shown in bold.
aThese animals were not recorded on SIL at the time of analysis, but belonged to flocks with these breed designations.
