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.

Genetic distance, in simple terms, is the number of alleles at which two individuals differ. For example, matches at 111/111 markers have a genetic distance of 0, while matches at 21/25 have a genetic distance of 4.
Understanding Y-DNA Genetic Distance. Genetic Distance (GD) refers to the total number of differences in the STR values of two different people. For example, if we look at 12 STRs and two people have the same values for all 12 markers, they have a GD of 0. There are two methods to determine the GD.
21 kwi 2021 · Figure 1 provides a general overview of gene-set distance analysis (GSDA). The initial inputs are a list of genes belonging to the gene set, gene expression matrix, and the endpoint, phenotype, or treatment data which is to be associated with the expression matrix (Fig. 1 a).
This guide applies to GenAlEx 6.5 onwards. It assumes a level of prior knowledge of population genetics likely held by an informed graduate student. The calculations performed by GenAlEx are detailed in a separate Appendix 1: Methods and statistics in GenAlEx 6.5, by Rod Peakall and Peter Smouse.
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.
