Query: A nearly-neutral biallelic Moran model with biased mutation and linear
  and quadratic selection   In this article, a biallelic reversible mutation model with linear and
quadratic selection is analyzed. The approach reconnects to one proposed by
Kimura ( Possibility of extensive neutral evolution under stabilizing selection
with special reference to nonrandom use of codons (PNAS,1981)), who starts from
a diffusion model and derives its equilibrium distribution up to a constant. We
use a boundary-mutation Moran model, which approximates a general mutation
model for small effective mutation rates, and derive its equilibrium
distribution for polymorphic and monomorphic variants in small to moderately
sized populations. Using this model, we show that biased mutation rates and
linear selection alone can cause patterns of polymorphism rates within and
substitution rates between populations that are usually ascribed to balancing
or overdominant selection. We illustrate this using a data set of short introns
and fourfold degenerate sites from Drosophila simulans and Drosophila
melanogaster.
