Each of the regulars exhibited selfish traits, particularly George, based on David himself.
Another possibility not accounted for by permutation is if our GR QTL actually resulted from "regular" QTL for trait mean where one allele of the causal variant was present at a ∼50% frequency in the high-dispersion genotype class, but not present in the low-dispersion class.
Earlier hominins were capable bipeds, but they also exhibit a suite of skeletal traits indicating regular arboreal climbing behavior.
"WoW seems to be offering opportunities to develop certain moral traits that regular life in contemporary society doesn't afford," Barrett says.
Though elephant shrews share many analogous traits with regular shrews, genetic homologies suggests that elephant shrews actually sprang from a much older (and perhaps more charismatic) branch of the tree of life the one belonging to elephants and their relatives: http://evolution.berkeley.edu/evolibrary/news/080301_elephantshrew.edu/evolibrary/news/080301_elephantshrew
Software used currently to approximate reliabilities for regular MACE uses single-trait equations but could be modified for GMACE to use multiple-trait equations instead.
Our study was founded on the solid expectation that we would find an association between known functional allelic variations in the dopaminergic signaling pathway and the narrow, but well-defined, trait of regular leisure time exercise behavior.
Nevertheless, in both species 'constant conditions' produced progressive decrease of fitness components with time of cultivation, while the stress induced at regular intervals maintained life-history traits stable in time.
Milder and more repetitive stresses, on the other hand, are expected to induce an adaptive change, and the role of stress in shaping the genetic architecture of life history traits is a regular problem in evolutionary biology [ 5, 6].
Freely available software like MACH2QTL/DAT (Li et al., 2006), SNPTEST (Marchini et al., 2007) or ProbABEL (Aulchenko et al., 2007) perform similarly well for these analyses and allow trivial parallelization for distributed computing: the computation time on a regular computer for one continuous trait (∼2.5 million markers, ∼6000 samples) is currently ∼6 h.
