On the Choice of Genetic Distance in Spatial-Genetic Studies [PDF]

Genetics, 2007
Abstract We look at how to choose genetic distance so as to maximize the power of detecting spatial structure. We answer this question through analyzing two population genetic models that allow for a spatially structured population in a continuous habitat.

Universal information distance for genetic programming

Proceedings of the Companion Publication of the 2014 Annual Conference on Genetic and Evolutionary Computation, 2014
This paper presents a genotype-level distance metric for Genetic Programming (GP) based on the symmetric difference concept: first, the information contained in individuals is expressed as a set of symbols (the content of each node, its position inside the tree, and recurring parent-child structures); then, the difference between two individuals is ...

TBEV Subtyping in Terms of Genetic Distance. [PDF]

Viruses, 2020
Currently, the lowest formal taxon in virus classification is species; however, unofficial lower-level units are commonly used in everyday work. Tick-borne encephalitis virus (TBEV) is a species of mammalian tick-borne flaviviruses that may cause encephalitis.

Can We Compare Effect Size of Spatial Genetic Structure Between Studies and Species Using Moran Eigenvector Maps?

Frontiers in Ecology and Evolution, 2021
As the field of landscape genetics is progressing toward comparative empirical studies and meta-analysis, it is important to know how best to compare the strength of spatial genetic structure between studies and species.

First Identification and Genetic Characterization of a Novel Duck Astrovirus in Ducklings in China

Frontiers in Veterinary Science, 2022
Four divergent groups of duck astroviruses (DAstVs) have been identified that infect domestic ducks. In March 2021, a fatal disease characterized by visceral urate deposition broke out in 5-day-old Beijing ducks on a commercial farm in Guangdong province,

On the precision of estimation of genetic distance [PDF]

Genetics Selection Evolution, 1999
This article gives a formal proof of a formula for the precision of estimated genetic distances proposed by Barker et al. which can be used in designing experimental sampling programmes. The derivation is given in the general multiallelic case using the Sanghvi distance. Two sources of sampling are considered, i.e.
