I guess that I've been unclear.  The math does not predict what will
happen.  The math applies only in retrospect about the outcome.  That
outcome being a shift in the proportion of heritable characteristics.

That shift occurs when some variants in a population (for whatever reason)
exhibit a consistently greater degree of reproductive success over several
generations--meaning that their offspring, carrying their particular
heritable traits, then make up a larger PROPORTION of the breeding
population.  This process is called evolution.

The only math that I'm talking about is proportion.  When one practices
selective breeding, one shifts the proportions of traits in the breed away
from the proportions in the wild type.  This doesn't necessarily require
novel mutations, but may.
