When asked about dominance and the selective advantage of traits, some students replied, Student C: Since g1 is dominant, and if it has been for some time, I would say it is selectively advantageous.
In summary, SHAVE takes advantage of multiple trait measurements to boost statistical power for GWAS of quantitative traits.
Just as it is tempting to take natural selection to extremes, it is tempting to look for the evolutionary advantage of any trait of an organism in other words, to see adaptations everywhere.
For example, Kopp (2009) has advocated a meta-model approach for evolutionary genetics that takes advantage of parallel trait changes in a clade to ask whether and why convergent phenotypes are underpinned by similar genetic changes.
The fact that selfing has arisen multiple, independent times within clade C may imply a selective advantage of this trait ([ 55, 92, 94]; see further below), and that inbreeding depression, as the principal counterweight to this advantage (e.g., [ 13, 14]), has not impeded the evolution of selfing in these tropical orchids.
Typically, studies on character evolution focus on either the potential advantages of a trait in a given environment [ 92- 94] or mechanisms that create novel phenotypes [ 95, 96].
Thus, "pre-adaptation" owing to phenotypic mutation would promote fixation of the second mutation which will be beneficial even without the first one – if the selective advantage of the complex trait is high enough (the ultimate situation that helps understanding is that this trait is essential for survival).
Mathematical modeling described in the paper shows that, if the selective advantage of the complex trait, i.e., the selection coefficient for the second mutation, is high enough, this look-ahead effect becomes realistic under the experimentally determined mistranslation rates.
Such changes in population density can thus alter the selective advantage of particular male traits, such as secondary sexual traits and body size that afford mating success.
The advantage of using functional traits instead of taxonomic composition (an entirely structural approach) of communities is bound to the a priori predictable response of traits to individual stressors, because each selection pressure affects different traits.
From the breeding aspect, hybrid rice provides the advantage of combining elite traits or genes from different types of parents, such as those from subspecies of indica and japonica, into a single variety.
