Rookie question: Do you mean that between a heifer and a bull from the same exceptional dam, the heifer is more likely to produce a heifer of equal quality to her dam than the bull is?That's why the great cow is hard to recreate through sons.
If so, would that be because (assuming an adequate sire) the heifer is adjacent to the dam, therefore (theoretically) already an improved version of the dam? Where the bull's heifer offspring would be a generation removed from his dam rather than adjacent?
