  The growing probabilities of additional offspring with the beneficial
reversal allele for various population sizes, $N$, sequence lengths, $L$,
selective advantages, $s$, fitness parameters, $k$, and measuring parameters,
$C$, were calculated in an asymmetric sharply-peaked landscape using the
decoupled continuous-time mutation-selection model. The growing probability in
the stochastic region was inversely proportional to the measuring parameter
when $C<1/Ns^*$, bent when $C\approx 1/Ns^*$ and became saturated when
$C>1/Ns^*$, where $s^*$ is the effective selective advantage. The saturated
growing probability in the stochastic region was approximately the effective
selective advantage when $C\gg 1/Ns^*$ and $s^*\ll 1$. The present study
suggests that the growing probability in the stochastic region in an asymmetric
sharply-peaked landscape in the decoupled continuous-time mutation-selection
model can be described using the theoretical formula for the growing
probability in the Moran two-allele model. The selective advantage ratio, which
represents the ratio of the effective selective advantage to the selective
advantage, does not depend on the population size, selective advantage,
measuring parameter, and fitness parameter; instead the selective advantage
ratio decreases with increasing the sequence length.
