Here W2N represents a multidimension surface of mean selective values relative
to the frequencies of genes at all loci in an interaction system. There must be
numerous peaks, saddles, and pits in this surface to provide the basis for a ...

The mean (w) of the relative selective values assigned genotypes in a population
is a parameter that is primarily useful in connection with estimates of the rates of
change of gene frequencies. Its value is always relative to an arbitrary choice of ...
