When the heterozygote has the lowest fitness, the A allele rises in frequency if it is common or decreases in frequency if it is rare: The cut-off between where A rises or drops is called an …

The parameter region where a stable polymorphic equilibrium is maintained changes when a subpopulation's density fluctuates (Fig. 6: solid versus dashed lines)—but the stabilizing effect …

We show that constant frequency-independent selection with arbitrary epistasis on a well-mixed haploid population eliminates genetic variation if we assume linkage equilibrium between alleles.

Nov 6, 2023 · Rapid evolution can occur when there is considerable genetic polymorphism at selected loci. We propose that balancing selection could be one of the mechanisms that …

Aug 1, 1980 · There exists a symmetric polymorphism; we delimit its level of heterozygosity and stability nature (dependent on the selection intensities and assorting propensities). This …

polymorphic equilibrium offers a sensible explanation for the existence of strategic groups within industries. Unlike the existing literature on strategic groups, this article focuses on

We find that FDS maintains full polymorphism more often than classic constant-selection models and produces more skewed equilibrium allele frequencies.

For any polymorphic equilibrium, 0 < J < 1, expression (5) indicates that a and b must be the same sign and therefore that the heterozygote cannot be intermedi-ate in fitness at the …

Oct 25, 2016 · Asymptotic stability of equilibrium in evolutionary games with continuous action spaces is an important question. Existing results in the literature require that the equilibrium …

Feb 5, 2019 · For example, a stable polymorphic equilibrium can be expected if β is an order of magnitude larger than the parameter σ, in which case the net growth rate advantage of …
