Fitness and its role in evolutionary genetics [PDF]
Nature Reviews Genetics, 2009 Although the operation of natural selection requires that genotypes differ in fitness, some geneticists may find it easier to understand natural selection than fitness. Partly this reflects the fact that the word 'fitness' has been used to mean subtly different things.

Global Amphibian Declines, Loss of Genetic Diversity and Fitness: A Review
Diversity, 2010 It is well established that a decrease in genetic variation can lead to reduced fitness and lack of adaptability to a changing environment. Amphibians are declining on a global scale, and we present a four-point argument as to why this taxonomic group ...

Genetic complementation fosters evolvability in complex fitness landscapes
Scientific Reports, 2023 The ability of natural selection to optimize traits depends on the topology of the genotype-fitness map (fitness landscape). Epistatic interactions produce rugged fitness landscapes, where adaptation is constrained by the presence of low-fitness ...

Intralocus sexual conflict diminishes the benefits of sexual selection. [PDF]
PLoS Biology, 2006 Evolution based on the benefits of acquiring "good genes" in sexual selection is only plausible with the reliable transmission of genetic quality from one generation to the next.

Balanced genetic diversity improves population fitness [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2018 Although genetic diversity within a population is suggested to improve population-level fitness and productivity, the existence of these effects is controversial because empirical evidence for an ecological effect of genetic diversity and the underlying mechanisms is scarce and incomplete.

A GENETIC ALGORITHM FOR FACE FITTING [PDF]
Proceedings of the International Conference on Computer Graphics Theory and Applications, 2012 Accurate estimation of the shape of human faces has many applications from the movie industry to psychological research. One well known method is to fit a Three Dimensional Morphable Model to a target image. This method is attractive as the faces it constructs are already projected onto an orthogonal basis making further manipulation and analysis ...

The Journal of Poultry Science, 2003 Establishment of small body size poultry is an important strategy, which leads to effective management of bird-colonies and less feed consumption. And also it would be a useful experimental tool for elucidating an evolutionary mechanism causing the ...

A simple completion of Fisher’s fundamental theorem of natural selection
Ecology and Evolution, 2021 Fisher's fundamental theorem of natural selection shows that the part of the rate of change of mean fitness that is due to natural selection equals the additive genetic variance in fitness.

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]
, 2013 To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare.

BMC Evolutionary Biology, 2008 Background Quantifying the amount of standing genetic variation in fitness represents an empirical challenge. Unfortunately, the shortage of detailed studies of the genetic architecture of fitness has hampered progress in several domains of evolutionary ...
