Jan 29, 2019 · Sexually concordant dominance variance, SA additive variance, and SA dominance variance were the primary components of overall fitness variation in the population—consistent with the hypothesis that balancing selection and dominance reversals contribute to the maintenance of fitness variation.

Jan 10, 2022 · Some important open questions are how much dominance affects the fitness of women, and whether the dominance cues in women are identical to those that strongly affect assessed dominance in men.
fitness (life history) had significantly higher dominance components than did traits more distantly related to fitness (morphology) for wild species. No significant differences were found

Mar 13, 2024 · The final two studies we highlight both identified dominance reversals in major-effect autosomal inversion polymorphisms that underlie life history traits with sex-specific fitness optima. Both examples involve the interplay between life history trade-offs, environmental effects and sex- or trait-specific dominance reversals combining to ...
The population genetics community has explored the conditions under which natural selection acts on dominance interactions at the level of organismal fitness. These generic models largely neglected the molecular processes underlying these interactions.
In practice, approximations are used such as GMF ≈ μ-σ2/μ, where µ is the arithmetic mean fitness and σ 2 is the variance in fitness. This formula explicates the fact that natural selection favors increases in mean fitness, but also decreases in the variance of fitness.

Jan 8, 2015 · Additive variance in fitness components can be maintained in the absence of V A for net fitness by processes such as frequency-dependent selection or antagonistic effects of alleles on different fitness components, given suitable conditions on the dominance coefficients for the effects of the variants on the traits in question .
