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.

The quantitative genetics of fitness in a wild seabird
Evolution, 2021 Additive genetic variance in fitness is a prerequisite for adaptive evolution, as a trait must be genetically correlated with fitness to evolve. Despite its relevance, additive genetic variance in fitness has not often been estimated in nature. Here, we investigate additive genetic variance in lifetime and annual fitness components in common terns ...

Semantically Driven Mutation in Genetic Programming [PDF]
, 2008 Using semantic analysis, we present a technique known as semantically driven mutation which can explicitly detect and apply behavioural changes caused by the syntactic changes in programs that result from the mutation operation. Using semantically driven

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 ...

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.

Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]
, 2009 Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.

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,

Rare-event sampling analysis uncovers the fitness landscape of the genetic code.
PLoS Computational Biology, 2023 The genetic code refers to a rule that maps 64 codons to 20 amino acids. Nearly all organisms, with few exceptions, share the same genetic code, the standard genetic code (SGC).

Genetics of somatotype and physical fitness in children and adolescents [PDF]
American Journal of Human Biology, 2020 AbstractObjectivesTo analyze the influence of genetic and environmental factors on the variation in somatotype, physical fitness, and their mutual associations.MethodsTwins from 214 pairs (87 monozygotic) of the Autonomous Region of Madeira, Portugal, from 3 to 18 years of age (51% girls) were assessed in anthropometry and physical fitness tests.
