Input consists of raw data or distance matrices in appropriate GenAlEx format (see the ‘Data Format in GenAlEx’ section). In order to proceed with an analysis the worksheet containing the data must be activated (visible). Some analyses and procedures take several worksheets as input.
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).
Tutorial 1 (zip 6.9 mb) An Introduction to Frequency-Based Population Genetic Analysis: scoring genetic markers, Allele Frequency, Heterozygosity, F-statistics, Nei Genetic Distance, Shannon Diversity Indices and Chi-square tests for Hardy-Weinberg Equilibrium.
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.
1 gru 2013 · The comparison of genetic divergence or genetic distances, estimated by pairwise FST and related statistics, with geographical distances by Mantel test is one of the most popular approaches...
1 lut 2005 · Mantel tests of matrix correspondence have been widely used in population genetics to examine microevolutionary processes, such as isolation-by-distance (IBD). We used partial and...
19 gru 2006 · We describe a method for testing the relationship between variation in a distance matrix and predictor information collected on the samples whose gene expression levels have been used to construct the matrix.
