We reconsider the deterministic haploid mutation–selection equation with two types. This is an ordinary differential equation that describes the type distribution (forward in time) in a population of infinite size. This paper establishes ancestral (random) structures inherent in this deterministic model. In a first step, we obtain a representation of the deterministic equation’s solution (and, in particular, of its equilibria) in terms of an ancestral process called the killed ancestral… 
Solving the selection-recombination equation: Ancestral lines under selection and recombination
This contribution uses a probabilistic, genealogical approach for the case of an \emph{arbitrary} number of neutral sites that are linked to one selected site to obtain a stochastic representation of the deterministic solution, along with the Markov semigroup in closed form.
Lines of descent in the deterministic mutation-selection model with pairwise interaction
With the help of the stratified ancestral selection graph, the mutation-selection differential equation with pairwise interaction is considered and results about the ancestral type distribution in the case of unidirectional mutation are obtained.
Lines of Descent Under Selection
We review recent progress on ancestral processes related to mutation-selection models, both in the deterministic and the stochastic setting. We mainly rely on two concepts, namely, the killed
Lines of descent in a Moran model with frequency-dependent selection and mutation
We consider the two-type Moran model with frequency-dependent selection and two-way mutation, where selection follows either the nonlinear dominance or the fittest-type-wins scheme, which will turn

Ancestral lines under recombination
With the help of an ancestral partitioning process, which is obtained by letting population size tend to infinity (without rescaling parameters or time) in an ancestral recombination graph, the solution to the recombination equation is obtained in a transparent form.
The general labelled partitioning process in action: recombination, selection, mutation, and more
This work aims to unify and generalise a recursive construction of the solution of the selectionrecombination equation by introducing a new labelled partitioning process with general Markovian labels.
Microbial populations under selection
A model of a host-pathogen system where the population of pathogenes experiences balancing selection, migration, and mutation, as motivated by observations of the genetic diversity of HCMV (the human cytomegalovirus) across hosts is described.
Plasmid stability in fluctuating environments: population genetics of multi-copy plasmids
It is argued that plasmid copy number is a highly optimized evolutionary trait that depends on the rate of environmental fluctuation and balances the benefit between increased stability in the absence of selection with the burden associated with carrying multiple copies of the plasmids.


The Common Ancestor Process for a Wright-Fisher Diffusion
This work describes the process of substitutions to the common ancestor of each population using the structured coalescent process introduced by Kaplan et al. (1988), and shows that the theory can be formally extended to diffusion models with more than two genetic backgrounds, but that it leads to systems of singular partial differential equations which it is unable to solve.
The common ancestor type distribution of a $\Lambda$-Wright-Fisher process with selection and mutation
A strong pathwise Siegmund dual is identified of the ancestor in a two-type Wright-Fisher population with mutation and selection, conditional on the overall type frequency in the old population, and the equilibrium tail probabilities of $L$ are characterised in terms of hitting probabilities of the dual process.
Ancestral Processes with Selection
The main goal is to analyze the ancestral selection graph and to compare it to Kingman's coalescent process; it is found that the distribution of the time to the most recent common ancestor does not depend on the selection coefficient and hence is the same as in the neutral case.

Bifurcations in haploid and diploid sequence space models
Abstract. Deterministic models of mutation and selection in the space of (binary) nucleotide-type sequences have been investigated for haploid populations during the past 25 years, and, recently, for
Supercritical multitype branching processes: the ancestral types of typical individuals
For supercritical multitype Markov branching processes in continuous time, the evolution of types along those lineages that survive up to some time t is investigated, and almost-sure convergence theorems for both time and population averages of ancestral types are established.
The deterministic limit of the Moran model: a uniform central limit theorem
We consider a Moran model with two allelic types, mutation and selection. In this work, we study the behaviour of the proportion of fit individuals when the size of the population tends to infinity,
