Fixation of a Deleterious Allele under Mutation Pressure and Finite Selection Intensity [PDF]

, 2011
The mean fixation time of a deleterious mutant allele is studied beyond the diffusion approximation. As in Kimura's classical work [M. Kimura, Proc. Natl. Acad. Sci. U.S.A.

RETRACTED: An innovative panel containing a set of insertion/deletion loci for individual identification and its forensic efficiency evaluations in Chinese Hui ethnic minority

Molecular Genetics & Genomic Medicine, 2020
Background Individual identification is one of the most important tasks in the field of forensic genetics. Insertion/Deletion (InDel) polymorphism marker has been a promising marker for individual identification. However, a part of InDel loci in commonly

Muller's ratchet and mutational meltdowns [PDF]

, 1993
We extend our earlier work on the role of deleterious mutations in the extinction of obligately asexual populations. First, we develop analytical models for mutation accumulation that obviate the need for time-consuming computer simulations in certain ...

Fixation and consensus times on a network: a unified approach

, 2008
We investigate a set of stochastic models of biodiversity, population genetics, language evolution and opinion dynamics on a network within a common framework. Each node has a state, 0 < x_i < 1, with interactions specified by strengths m_{ij}.

Genetic Diversity and Structure of Calophyllum brasiliense Along the Santa Catarina Coast

Floresta e Ambiente, 2019
Population genetics studies can provide knowledge in support of conservation efforts for plant populations. We studied the genetic diversity and structure in nine populations of Calophyllum brasiliense from Santa Catarina state, Brazil, aiming to ...

Robust forward simulations of recurrent hitchhiking [PDF]

, 2014
Evolutionary forces shape patterns of genetic diversity within populations and contribute to phenotypic variation. In particular, recurrent positive selection has attracted significant interest in both theoretical and empirical studies.

On the stochastic evolution of finite populations [PDF]

, 2016
This work is a systematic study of discrete Markov chains that are used to describe the evolution of a two-types population. Motivated by results valid for the well-known Moran (M) and Wright-Fisher (WF) processes, we define a general class of Markov chains models which we term the Kimura class.

Population dynamics in compressible flows

, 2012
Organisms often grow, migrate and compete in liquid environments, as well as on solid surfaces. However, relatively little is known about what happens when competing species are mixed and compressed by fluid turbulence.

A new method for ecologists to estimate heterozygote excess and deficit for multi‐locus gene families

Ecology and Evolution
The fixation index, FIS, has been a staple measure to detect selection, or departures from random mating in populations. However, current Next Generation Sequencing (NGS) cannot easily estimate FIS, in multi‐locus gene families that contain multiple loci

Development and characterization of microsatellite markers for Antennaria corymbosa (Asteraceae) and close relatives

Applications in Plant Sciences, 2019
Premise The genus Antennaria has a complex evolutionary history due to dioecism, excessive polyploidy, and the evolution of polyploid agamic complexes. We developed microsatellite markers from A.
