Sharp Bounds for Genetic Drift in Estimation of Distribution Algorithms [PDF]
IEEE Transactions on Evolutionary Computation, 2019 Estimation of distribution algorithms (EDAs) are a successful branch of evolutionary algorithms (EAs) that evolve a probabilistic model instead of a population.

Ecology and Evolution, 2021 The presence of shell bands is common in gastropods. Both the marine snails Littorina fabalis and Lttorina saxatilis are polymorphic for this trait. Such polymorphism would be expected to be lost by the action of genetic drift or directional selection ...

Management of Genetic Diversity in the Era of Genomics
Frontiers 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
Journal 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.

Observing populations and testing predictions about genetic drift in a computer simulation improves college students’ conceptual understanding [PDF]
Evolution: Education and Outreach, 2016 BackgroundEvolution is a difficult subject for students, with well-documented confusion about natural selection, tree thinking, and genetic drift among other topics.

Evolutionary 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]
PLoS 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 ...

Assessment of genetic drift and migration in six cattle breeds [PDF]
Acta Fytotechnica et Zootechnica, 2020 Slovak Spotted cattle represents an endangered breed with cultural importance in Slovakia. The study was based on the panel of 34,604 SNPs that were used for genotyping of 451 individuals.

Effects of multiple sources of genetic drift on pathogen variation within hosts
bioRxiv, 2017 Changes in pathogen genetic variation within hosts alter the severity and spread of infectious diseases, with important implications for clinical disease and public health.

Genetic drift in range expansions is very sensitive to density dependence in dispersal and growth.
Ecology Letters, 2019 Theory predicts rapid genetic drift during invasions, yet many expanding populations maintain high genetic diversity. We find that genetic drift is dramatically suppressed when dispersal rates increase with the population density because many more ...
