Population genetics of Enterocytozoon bieneusi in captive giant pandas of China

open access: yesParasites & Vectors, 2017
Background Most studies on Enterocytozoon bieneusi are conducted based on the internal transcribed spacer (ITS) region of the rRNA gene, whereas some have examined E. bieneusi population structures.

The clarifying role of time series data in the population genetics of HIV.

open access: yesPLoS Genetics, 2021
HIV can evolve remarkably quickly in response to antiretroviral therapies and the immune system. This evolution stymies treatment effectiveness and prevents the development of an HIV vaccine.

Population Growth Combined with Wide Offspring Distributions can Increase Fixation Rate and Reduce Genetic Diversity

open access: yesBulletin of Mathematical Biology, 2016
Genetic diversity grows with the population size in most neutral evolution models. Empirical evidence of large populations with limited diversity has been proposed to be due either to genetic bottlenecks or to selection. An alternative explanation is that the limited diversity is a result of rare reproduction events.

Haplotypic polymorphisms and forensic applications in Chinese Hunan Han population based on a series of Y-STR loci: a perspective of paternal inheritance

open access: yesAnnals of Human Biology, 2023
Background Hunan, a multinational province in China, possesses more than fifty ethnic groups, such as the Han, Yao, Tujia, Miao, and so on. Aims To evaluate the forensic efficiency of the novel panel and investigate the genetic relationships between ...

Structural and Temporal Variation in Genetic Diversity of European Spring Two-Row Barley Cultivars and Association Mapping of Quantitative Traits

open access: yesThe Plant Genome, 2013
Two hundred sixteen barley ( L.) cultivars were selected to represent the diversity and history of European spring two-row barley breeding and to search for alleles controlling agronomic traits by association genetics.

Hitchhiking to speciation. [PDF]

open access: yesPLoS 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

Genotype by random environmental interactions gives an advantage to non-favored minor alleles

open access: yesScientific 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]

open access: yesPLoS 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.

Hybrid fitness effects modify fixation probabilities of introgressed alleles

open access: yesG3: Genes, Genomes, Genetics, 2022
Hybridization is a common occurrence in natural populations, and introgression is a major source of genetic variation. Despite the evolutionary importance of adaptive introgression, classical population genetics theory does not take into account hybrid ...

Fixation of genetic variation and optimization of gene expression: The speed of evolution in isolated lizard populations undergoing Reverse Island Syndrome

open access: yesPLOS ONE, 2019
The ecological theory of island biogeography suggests that mainland populations should be more genetically divergent from those on large and distant islands rather than from those on small and close islets. Some island populations do not evolve in a linear way, but the process of divergence occurs more rapidly because they undergo a series of ...
