Proportions of genetic contributions for different trait categories from ram selection in the multiplier flock as expressed in the self-replacing commercial ewe flock in years after recording and genotyping were introduced. Number of years from when a ram is first mated in the commercial tier. ɛ L = lamb birth traits, ɛ S = lamb slaughter traits, ɛ H = hogget traits and ɛ A = annual ewe traits
