Heritabilities, commonly used to predict evolutionary potential, are notoriously low for behaviors. Apart from strong contributions of environmental variance in reducing heritabilities, the additive genetic components can be very low, especially when they are camouflaged by nonadditive genetic effects. We first report the heritabilities of courtship traits in founder‐flush and control populations of the housefly (Musca domestica L.). We estimated the heritability of each male and female display… 

Social cues affect quantitative genetic variation and covariation in animal personality traits

It is concluded that the social environment can have a significant impact on the heritability and evolvability of behavior, and it is argued that evolutionary inferences from phenotypic studies should be made with caution.

A dataset comprised of over 1,000 genomic loci representing a spectrum of behavioral variation across animal taxa provides evidence that different types of behavior are associated with variable genetic bases and suggests that the genetic landscape of behavior is more rugged, yet predictable, than previously thought.

Genotype × environment interaction for male attractiveness in an acoustic moth: evidence for plasticity and canalization

It is argued that variation persists in natural populations because G’× E interactions prevent any one variant from producing the optimal phenotype across all environments.

Heritability, selection, and the response to selection in the presence of phenotypic measurement error: effects, cures, and the role of repeated measurements

It is presented how in a continuous trait transient effects with a classical measurement error structure may bias estimates of heritability, selection gradients, and the predicted response to selection, and how the inclusion of the corresponding variance components in quantitative genetic models yields unbiased estimates of all quantities of interest.

Investigations of whole-genome sequencing and phenotypic data for 87 behavioral traits from the Drosophila Genetics Reference Panel indicate that courtship and feeding behaviors have significantly greater genetic contributions and that, in general, behavioral traits overlap little in individual base pairs but increasingly interact at the levels of genes and traits.

The contribution of additive genetic variation to personality variation: heritability of personality

It is demonstrated that genetic differences are likely to be a major contributor to variation in animal personality and support the phenotypic gambit: that evolutionary inferences drawn from repeatability estimates may often be justified.

Heritability is not Evolvability

The correlation between heritability and evolvability is essentially zero, and it is argued that this is likely due to inherent positive correlations between the additive variance and other components of phenotypic variance.

The results suggest that reductionist approaches of molecular behavior genetics may be incomplete and/or misleading when considering similar phenotypes at the population level or when trying to understand how behaviors evolve.

Bottleneck effects on genetic variance for courtship repertoire.

Nonadditive genetic effects on mating behavior may be important in structuring genetic variance for courtship, although most of the increases in genetic variance would be expected to reflect inbreeding depression with relatively rare situations representing the facilitation of speciation by bottlenecks.

A test of how well the repeatability of courtship predicts its heritability

It is demonstrated that repeatabilities are labile within individuals and may actually underestimate heritabilities when there is a genetic predisposition not to repeat performance, concur with related studies that repeatability can identify evolutionary potential, but advise caution in interpreting low values or comparing their absolute values.

Heritability and ‘evolvability’ of fitness components in Callosobruchus maculatus

The results resemble those from a recent survey of Drosophila studies and suggest that the typically low heritabilities of behavioural or life-history traits are better explained by high residual variation than by low additive-genetic variation.

Laboratory and natural heritabilities of male courtship song characters in Drosophila montana and D. littoralis

The heritabilities for several male courtship song characters in two Drosophila species using father-son regression under conditions where both fathers and sons had been raised in the laboratory appeared to be low, due to larger phenotypic variability ofsong characters in the field and in some cases also due to genotype-environment interactions.

Design and analysis of experiments on random drift and inbreeding depression.

In general, it appears that the authors can best understand the response of populations to inbreeding and finite population size by studying a very large number of self-fertilizing or full-sib mated lines in parallel with one or more stable control populations.
