28 lis 2019 · Summarizing and visually representing these patterns of diversity has been a persistent goal for human geneticists, and has revealed that genetic differentiation is frequently correlated with geographic distance.
To choose a genetic distance and a pruning method for the genetic graph construction, we developed functions to perform preliminary analyses of the spatial pattern of genetic differentiation.
In this article, we discuss the basic graph theory concepts and the various graph types, as well as the available data structures for storing and reading graphs. In addition, we describe several network properties and we highlight some of the widely used network topological features.
This chapter introduces some of the methodologies used in estimating genetic distances, how we analyze them, and how we portray our results in a graphical fashion amenable for interpretation. Underlying most estimates of genetic distance are sets of geometric and/or evolutionary assumptions.
25 wrz 2008 · McRae (2006) and Brooks (2006) incorporated genetics and graph theory into analyses of isolation by distance that incorporate landscape heterogeneity and understanding scales of population organization and movement among patches, respectively.
20 cze 2023 · A genetic map shows the map distance, in cM, that separates any two loci, and the position of these loci relative to all other mapped loci. The genetic map distance is roughly proportional to the physical distance, i.e. the amount of DNA between two loci.
29 kwi 2014 · For the GEN data set, the genetic distances Δ GEO (X, Y) between two individuals with known latitude and longitude were calculated using the Haversine formula 47: , where R is the radius of...
