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.

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.
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.
(A) Calculate Distance Matrix: Start with two FASTA files of the DNA coding sequences of two species. For each species, find the unused codons within each gene, alphabetize them, and make those...
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.
We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency. By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.
