The analysis of FSH beta-subunit gene genotypes in East Anatolian Red, East Anatolian Red×Holstein, and Zavot bulls

open access: yesOpen Veterinary Science, 2021
This study aimed to investigate the genotypic distribution and population genetic parameters of the single nucleotide polymorphism (SNP) located on exon 3 at the FSHB gene in East Anatolian Red (EAR), East Anatolian Red×Holstein (EAR×H), and Zavot (Z ...

Evolutionary dynamics in fluctuating environment

open access: yesPhysical Review Research, 2020
Temporal environmental variations are ubiquitous in nature, yet most of the theoretical works in population genetics and evolution assume fixed environment.

Understanding evolutionary and ecological dynamics using a continuum limit

open access: yesEcology and Evolution, 2021
Continuum limits in the form of stochastic differential equations are typically used in theoretical population genetics to account for genetic drift or more generally, inherent randomness of the model. In evolutionary game theory and theoretical ecology,

The molecular clock of neutral evolution can be accelerated or slowed by asymmetric spatial structure. [PDF]

open access: yesPLoS Computational Biology, 2015
Over time, a population acquires neutral genetic substitutions as a consequence of random drift. A famous result in population genetics asserts that the rate, K, at which these substitutions accumulate in the population coincides with the mutation rate ...

Phenotypic heterogeneity in modeling cancer evolution. [PDF]

open access: yesPLoS ONE, 2017
The unwelcome evolution of malignancy during cancer progression emerges through a selection process in a complex heterogeneous population structure. In the present work, we investigate evolutionary dynamics in a phenotypically heterogeneous population of

Mating system and speciation I: Accumulation of genetic incompatibilities in allopatry.

open access: yesPLoS Genetics, 2022
Self-fertilisation is widespread among hermaphroditic species across the tree of life. Selfing has many consequences on the genetic diversity and the evolutionary dynamics of populations, which may in turn affect macroevolutionary processes such as ...

Hydrodynamic flow and concentration gradients in the gut enhance neutral bacterial diversity [PDF]

open access: yesProc. Natl. Acad. Sci. U.S.A., 119(1): e2108671119 (2022), 2021
The gut microbiota features important genetic diversity, and the specific spatial features of the gut may shape evolution within this environment. We investigate the fixation probability of neutral bacterial mutants within a minimal model of the gut that includes hydrodynamic flow and resulting gradients of food and bacterial concentrations.

Wright-fisher-like models with constant population size on average [PDF]

open access: yes, 2017
We first recall some basic facts from the theory of discrete-time Markov chains arising from two types neutral and non-neutral evolution models of population genetics with constant size.

Genetic Structure of the Ca Rater Mallorquí Dog Breed Inferred by Microsatellite Markers

open access: yesAnimals, 2022
Ca Rater Mallorquí is a dog breed from the Island of Mallorca (Spain) traditionally used as a hunting and ratting dog to prevent disease spread and economic losses related to rodent activities on farms. However, the census data shows a population decline
