The Geographic Distance Matrix Generator is a platform-independent Java application that implements the same powerful suite of spherical functions as the Perpendicular Distance Calculator to compute all pair wise distances from a simple list of geographic coordinates.
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.

Select an input sequence. Use one of the following three fields: To access a sequence from a database, enter the USA here:
There are a variety of ways to calculate genetic distance, and the main function in this package, gen_dist(), allows a user to choose from five different genetic distances and saves square distance matrices as csv files.
11 gru 2023 · --ibs-test and --groupdist consider three subsets of the distance matrix: pairs of affected samples, affected-unaffected pairs, and pairs of unaffected samples.
24 maj 2017 · In this simulation study, we analyze the behavior of different genetic distances in Island (null hypothesis) and stepping stone models displaying varying neighborhood sizes. Impact of null...
It is often common in population genetics to estimate pairwise distance matrices representing difference in quantities such as spatial location, phenological overlap, genetic differentiation, ecological separation.
