Fisherian mechanism
WebThe Fisherian mechanism is, in essence, based only on genes that inßuence mating preferences and preferred traits, and it can lead to their rapid coevolution if the most preferred males are polygynous (e.g. [2,5,10,17] ). Genetic indicator mechanisms, however ,depend on overall quality and hence on much or most of the functional genome; they WebMechanisms. As of 2024 five proposed mechanisms address the evolution of mate …

WebFeb 5, 2016 · These very low rates may be pulling inflation and inflation expectations lower via the neo-Fisherian mechanism. That seems extremely unlikely, given that the markets respond to news of a surprise Fed rate increase in a way that suggests the market views this policy as disinflationary. Webwhich constitutes the basic mechanism for maintaining the Fisherian sex ratio of 1:1. In this sense, the sex-ratio problem is an example of conflict between individual and collective interests [4]. The Fisherian mechanism has many subtleties, and still not much is known about devia-tions from its prediction [5, 6].

WebIn normal sexual reproduction, a gene that is "fair" has 0.5 + 0.5p chance of being passed on to the next generation (where p is the proportion of the population that has the gene). This kind of reproduction does not alter the frequency of the gene in the population. I think that a Fisherian runaway occurs when a gene (or genes) cheats the system.
