Hitchhiking to speciation. [PDF]
PLoS Biology, 2013 The modern evolutionary synthesis codified the idea that species exist as distinct entities because intrinsic reproductive barriers prevent them from merging together. Understanding the origin of species therefore requires understanding the evolution and

Journal of Horticultural Science, 2022 Understanding gene action of different traits is of utmost importance for formulating successful breeding programs. The population was developed involving Arka Neelachal Shyama and CARI-1 to inquire the gene actions controlling the inheritance of several

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.

Fixation and Polarization in a Three-Species Opinion Dynamics Model [PDF]
, 2011 Motivated by the dynamics of cultural change and diversity, we generalize the three-species constrained voter model on a complete graph introduced in [J. Phys. A 37, 8479 (2004)].

Fluctuating selection models and Mcdonald-Kreitman type analyses [PDF]
, 2013 It is likely that the strength of selection acting upon a mutation varies through time due to changes in the environment. However, most population genetic theory assumes that the strength of selection remains constant.

Genotype by random environmental interactions gives an advantage to non-favored minor alleles
Scientific Reports, 2017 Fixation probability, the probability that the frequency of a newly arising mutation in a population will eventually reach unity, is a fundamental quantity in evolutionary genetics.

Simulating population genetics of pathogen vectors in changing landscapes: guidelines and application with Triatoma brasiliensis. [PDF]
PLoS Neglected Tropical Diseases, 2014 BACKGROUND:Understanding the mechanisms that influence the population dynamics and spatial genetic structure of the vectors of pathogens infecting humans is a central issue in tropical epidemiology.

Fixation properties of subdivided populations with balancing selection [PDF]
Phys. Rev. E 91, 032130 (2015), 2014 In subdivided populations, migration acts together with selection and genetic drift and determines their evolution. Building up on a recently proposed method, which hinges on the emergence of a time scale separation between local and global dynamics, we study the fixation properties of subdivided populations in the presence of balancing selection.

Population genetics in compressible flows. [PDF]
Physical Review Letters, 2011 We study competition between two biological species advected by a compressible velocity field. Individuals are treated as discrete Lagrangian particles that reproduce or die in a density-dependent fashion.

Bacteriophages limit the existence conditions for conjugative plasmids [PDF]
, 2015 Bacteriophages are a major cause of bacterial mortality and impose strong selection on natural bacterial populations, yet their effects on the dynamics of conjugative plasmids have rarely been tested.
