We analyse a family of two-types Wright-Fisher models with selection in a random
environment and skewed offspring distribution. We provide a calculable criterion to quantify …

Moran models and Wright–Fisher diffusions with selection and mutation in a one-sided random environment

F Cordero, G Véchambre - Advances in Applied Probability, 2023 - cambridge.org
Consider a two-type Moran population of size N with selection and mutation, where the
selective advantage of the fit individuals is amplified at extreme environmental conditions …

[HTML][HTML] The distribution of the quasispecies for the Wright–Fisher model on the sharp peak landscape

J Dalmau - Stochastic Processes and their Applications, 2015 - Elsevier
We consider the classical Wright–Fisher model with mutation and selection. Mutations occur
independently in each locus, and selection is performed according to the sharp peak …

The Wright–Fisher model for class–dependent fitness landscapes

J Dalmau - Electronic Journal of Probability, 2021 - projecteuclid.org
We consider a population evolving under mutation and selection. The genotype of an
individual is a word of length ℓ over a finite alphabet. Mutations occur during reproduction …

[PDF][PDF] Modelling selection via multiple ancestors

AG Casanova, D Spano - arXiv preprint arXiv:1612.04947, 2016 - researchgate.net
A two-types, discrete-time population model with finite, constant size is constructed, allowing
for a general form of frequency-dependent selection and skewed offspring distribution …

Ancestral processes with selection: Branching and Moran models

E Baake, R Bialowons - arXiv preprint q-bio/0702002, 2007 - arxiv.org
We consider two versions of stochastic population models with mutation and selection. The
first approach relies on a multitype branching process; here, individuals reproduce and …

Inference from the stationary distribution of allele frequencies in a family of Wright–Fisher models with two levels of genetic variability

JM Ferguson, EO Buzbas - Theoretical population biology, 2018 - Elsevier
The distribution of allele frequencies obtained from diffusion approximations to Wright–
Fisher models is useful in developing intuition about the population level effects of …
