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.
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.
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.
1 cze 2022 · With an average read depth of 1, ngsDist overestimates genetic distance d when a relatively small true d is simulated (35-fold difference when true d = 0.01 ). This is due to ngsDist averaging over the posterior genotype distribution when calculating genetic distances (eq. 2 in Vieira et al. 2015). Averaging over the posterior leads to ...
1 mar 2002 · The primary use for plots of (genetic) isolation by (geographic) distance is to assess whether more distant population pairs are more different genetically. However, these plots can also be used to test the validity of simpler models of population structure (e.g., island or hierarchical island models).
