Population genetic structure in a self‐compatible hermaphroditic snail is driven by drift independently of its contemporary mating system [PDF]

open access: yesEcology and Evolution
Genetic drift, gene flow, and natural selection commonly influence population genetic diversity. In populations of self‐compatible hermaphrodites, the mating system (e.g., self‐fertilization) further reduces individual heterozygosity.

Management of Genetic Diversity in the Era of Genomics

open access: yesFrontiers in Genetics, 2020
Management of genetic diversity aims to (i) maintain heterozygosity, which ameliorates inbreeding depression and loss of genetic variation at loci that may become of importance in the future; and (ii) avoid genetic drift, which prevents deleterious ...

Mining frequent itemsets from streaming transaction data using genetic algorithms

open access: yesJournal of Big Data, 2020
This paper presents a study of mining frequent itemsets from streaming data in the presence of concept drift. Streaming data, being volatile in nature, is particularly challenging to mine.

Relatively rapid evolution rates of SARS-CoV-2 spike gene at the primary stage of massive vaccination

open access: yesBiosafety and Health, 2022
A series of stringent non-pharmacological and pharmacological interventions were implemented to contain the pandemic but the pandemic continues. Moreover, vaccination breakthrough infection and reinfection in convalescent coronavirus disease 2019 (COVID ...

Characterizing patterns of genomic variation in the threatened Utah prairie dog: Implications for conservation and management

open access: yesEvolutionary Applications, 2021
Utah prairie dogs (Cynomys parvidens) are federally threatened due to eradication campaigns, habitat destruction, and outbreaks of plague. Today, Utah prairie dogs exist in small, isolated populations, making them less demographically stable and more ...

Genetic and morphometric divergence of an invasive bird: the introduced house sparrow (Passer domesticus) in Brazil. [PDF]

open access: yesPLoS ONE, 2012
Introduced species are interesting systems for the study of contemporary evolution in new environments because of their spatial and temporal scales. For this study we had three aims: (i) to determine how genetic diversity and genetic differentiation of ...

Mapping genes through the use of linkage disequilibrium generated by genetic drift: 'Drift mapping' in small populations with no demographic expansion [PDF]

open access: yes, 1998
Linkage disequilibrium has been a powerful tool in identifying rare disease alleles in human populations. To date, most research has been directed to isolated populations which have undergone a bottleneck followed by rapid exponential expansion.

Identifying Parameters for Defining “Essentially Derived Varieties” of Maize Inbred Lines Using High-Throughput Genome-Wide SNP Markers

open access: yesPlants, 2022
Well-developed maize reference genomes and genotyping technology along with fast decreasing detection costs have enabled the chance of shifting essentially derived varieties (EDV) identification to high-throughput SNP genotyping technology.

Pattern formation through genetic drift at expanding population fronts [PDF]

open access: yes, 2010
We investigate the nature of genetic drift acting at the leading edge of range expansions, building on recent results in [Hallatschek et al., Proc. Natl. Acad. Sci., 104(50): 19926-19930 (2007)].

Antigenic drift in H5N1 avian influenza virus in poultry is driven by mutations in major antigenic sites of the hemagglutinin molecule analogous to those for human influenza virus [PDF]

open access: yes, 2011
H5N1 highly pathogenic avian influenza virus has been endemic in poultry in Egypt since 2008, notwithstanding the implementation of mass vaccination and culling of infected birds.
