Ecology and Evolution, 2022 Polyploid species possess more than two sets of chromosomes and may show high gene redundancy, hybrid vigor, and masking of deleterious alleles compared to their parent species.

Evolving cellular automata to generate nonlinear sequences with desirable properties [PDF]
, 2007 This paper presents a new chromosomal representation and associated genetic operators for the evolution of highly nonlinear cellular automata that generate pseudorandom number sequences with desirable properties ensured.

Good genes and sexual selection in dung beetles (Onthophagus taurus): genetic variance in egg-to-adult and adult viability. [PDF]
PLoS ONE, 2011 Whether species exhibit significant heritable variation in fitness is central for sexual selection. According to good genes models there must be genetic variation in males leading to variation in offspring fitness if females are to obtain genetic ...

Fitting Problems: Evaluating Model Fit in Behavior Genetic Models [PDF]
, 2021 Abstract In behavior genetics, like many fields, researchers must decide whether their models adequately explain their data – whether their models “fit” at some satisfactory level. Well-fitting models are compelling, whereas poorly-fitting models are not (Rodgers & Rowe, 2002).

Evolution Letters, 2021 Ongoing adaptive evolution, and resulting “evolutionary rescue” of declining populations, requires additive genetic variation in fitness. Such variation can be increased by gene flow resulting from immigration, potentially facilitating evolution.

Potential fitness for genetic programming [PDF]
Proceedings of the 10th annual conference companion on Genetic and evolutionary computation, 2008 We introduce potential fitness, a variant of fitness function that operates in the space of schemata and is applicable to tree-based genetic programing. The proposed evaluation algorithm estimates the maximum possible gain in fitness of an individual's direct offspring. The value of the potential fitness is calculated by analyzing the context semantics

Selection in males purges the mutation load on female fitness
Evolution Letters, 2021 Theory predicts that the ability of selection and recombination to purge mutation load is enhanced if selection against deleterious genetic variants operates more strongly in males than females. However, direct empirical support for this tenet is limited,

Discrete Evolutionary Genetics: Multiplicative Fitnesses and the Mutation-Fitness Balance
Applied Mathematics, 2011 We revisit the multi-allelic mutation-fitness balance problem especially when fitnesses are multiplicative. Using ideas arising from quasi-stationary distributions, we analyze the qualitative differences between the fitness-first and mutation-first models, under various schemes of the mutation pattern.

Enhancing genetic fitness while maintaining genetic variability in Araucaria angustifolia
Scientia Forestalis, 2021 Araucaria angustifolia provides timber, edible seeds and pharmaceuticals and has a unique ecology (once shared with that of the dinosaurs), yet is now threatened with extinction. Here, we assess and reconcile the counteracting goals of enhancing genetic fitness and maintaining genetic variability during ex-situ conservation of A.

Sex-specific dominance reversal of genetic variation for fitness.
PLoS Biology, 2018 The maintenance of genetic variance in fitness represents one of the most longstanding enigmas in evolutionary biology. Sexually antagonistic (SA) selection may contribute substantially to maintaining genetic variance in fitness by maintaining ...
