Rasmussen Factor

The Rasmussen Factor (RF) occurs when a horse can trace it's genetics to a common superior matriarch through different individuals, i.e. full or half siblings, within five generations (5x5 or closer). Thus the duplicate superior matriarch is traced to the horse via different individuals from the same dam.

FORMULA ONE PATTERN
Is when the individual's sire and dam both descend in tail-female line to the same superior matriarch.

DELTA PATTERN
Is when a stallion has one of his tail-male descendants bred to a superior matriarch who can trace in tail-female to a full sister to that stallion.
