Our focus here is on the infinitesimal model. In this model, one or several quantitative traits are described as the sum of a genetic and a non-genetic component, the first being distributed within families as a normal random variable centred at the average of the parental genetic components, and with a variance independent of the parental traits. Thus, the variance that segregates within families is not perturbed by selection, and can be predicted from the variance components. This does not… Expand
The effects of demography and genetics on the neutral distribution of quantitative traits
TLDR
This model allows interpretation of trait distributions in terms of familiar population genetic parameters because it is based on the coalescent, and shows how deviations from normality depend on demography through the distribution of coalescence times as well as through genetic parameters. Expand
The geometry and genetics of hybridization
TLDR
An analytical framework for predicting the fitness of hybrid genotypes, based on Fisher’s geometric model, provides a unifying framework for understanding speciation, and wider patterns of hybrid fitness. Expand
Comparison of infinitesimal and finite locus models for long-term breeding simulations with direct and maternal effects at the example of honeybees
TLDR
In the long-term, only the infinitesimal model predicted sustainable linear genetic progress, while the finite locus models showed sublinear behavior and, after 100 years, only reached between 58% and 62% of the mean breeding values in the inf initesimal models. Expand

Evolutionary dynamics of complex traits in sexual populations in a strongly heterogeneous environment: how normal?
TLDR
A mathematical framework that follows the whole trait distribution (without prior assumption) to study evolutionary dynamics of sexually reproducing populations and focuses on complex traits, whose inheritance can be encoded by the infinitesimal model of segregation (Fisher 1919). Expand
Ergodicity of the Fisher infinitesimal model with quadratic selection
We study the convergence towards a unique equilibrium distribution of the solutions to a time-discrete model with non-overlapping generations arising in quantitative genetics. The model describes theExpand
Animal models with group-specific additive genetic variances: extending genetic group models
TLDR
Simulations and an example from an insular meta-population of house sparrows in Norway with three genetic groups illustrate that the method is successful in estimating group-specific additive genetic variances and that segregation variances are indeed negligible in the empirical example. Expand
Polygenic adaptation after a sudden change in environment
TLDR
This work investigates the dynamics of this process, assuming that a sudden change in environment shifts the optimal value of a highly polygenic quantitative trait, and finds that when the shift is not too large relative to the genetic variance in the trait, the mean phenotype’s approach to the new optimum is well approximated by a rapid exponential process. Expand
A White Noise Approach to Evolutionary Ecology
TLDR
This approach contributes to the development of a synthetic theory of evolutionary ecology by formalizing first principle derivations of stochastic models that underlie rigorous investigations of the relationship between feedbacks of biological processes and the patterns of diversity they produce. Expand
Evolutionary perspectives on polygenic selection, missing heritability, and GWAS
TLDR
It is argued that “missing heritability” is as much an evolutionary problem as it is a statistical problem, and future statistical methods to infer causal loci for genetic traits will benefit from explicit modeling of the joint distribution of effect sizes and allele frequencies under plausible evolutionary models.

TLDR
The results on the limiting behaviour of population genetic models with many unlinked loci can be regarded as special cases of a more general limiting property of sequences of random variables. Expand
Genetic and statistical analyses of strong selection on polygenic traits: what, me normal?
TLDR
Data suggest that changes in genetic variance after 10 or more generations of selection are likely to be dominated by allele frequency dynamics that depend on genetic details, rather than the apparent simplicity of the infinitesimal limit. Expand

TLDR
Although the conditions under which drift is expected to increase VA are clarified, the evolutionary importance of such increases is questioned, and whether population bottlenecks lead to expected increases in additive variance depends primarily on the ratio of nonadditive to additive genetic variance in the base population.

TLDR
It is shown that the covariances, and hence the correlations, between relatives which are not inbred, can be expressed in terms of the components of genotypic variance. Expand
The Relation Between Reproductive Value and Genetic Contribution
TLDR
The central result is that the probability that a gene will survive is proportional to the reproductive value of the individual that carries it and that, conditional on survival, after a few tens of generations, the distribution of the number of surviving copies is the same for all individuals, whatever their reproductive value.

Evolution of continuous variation: direct approach through joint distribution of genotypes and phenotypes.
TLDR
It is proved that in the presence of selection the heritability,defined as the ratio of expected genotypic to expected phenotypic variance after selection, is greater than that before selection by a predictable amount and that it can be greater than unity. Expand
Estimation of variance components of quantitative traits in inbred populations.

The calculation of identity coefficients and estimation of variance components of quantitative traits in large inbred pedigrees, using the example of HDL in the Hutterites are described, using a multivariate normal model for the genetic effects and the central-limit theorem of Lange is extended.

Accounting for Mutation Effects in the Additive Genetic Variance-Covariance Matrix and Its Inverse
TLDR
Inclusion of the effects of mutation into an additive genetic mixed model seems important for the analysis of some animal breeding data and requires that account be taken of variances and covariances between animals accrued by mutations in previous generations, yet not traceable to the base population.

An Extension of the Concept of Partitioning Hereditary Variance for Analysis of Covariances among Relatives When Epistasis Is Present.
TLDR
The present paper shows the subdivision of the epistatic variance into components and gives the distribution of these epistatic components in the covariances or correlations between relatives. Expand
The analysis of variance and the correlations between relatives with respect to deviations from an optimum
TLDR
It appears that in a population in which the mean of some measurable character is at the optimum, the parent-offspring and fraternal correlations in adaptive value are approximately the squares of the corresponding correlations with respect to the character itself, whatever environmental complications there may be.
