What this part means

The complete quantity below the fraction bar; it must be nonzero for this division.

Its job in the formula

0.25/0.75 occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.

The passage around this formula

Suppose further that among the trait-positive horizontally exposed models, 70 percent produce a response diverging from the seeded canonical form beyond the declared threshold, μH\mu_H=0.70 , against 15 percent for the vertically exposed group, μV\mu_V=0.15 : horizontal transmission would be lossier, consistent with an indirect channel and with Mesoudi and Whiten’s finding that transmission-chain experiments on human cultural information typically show cumulative drift across successive links rather than the stable replication a simple copying model would predict [ 14 ] . And suppose a curation pass applied before the horizontally exposed artifact reached its downstream trainer moved the trait’s…
