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.

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. Define genetic distance. b. Know the origin of the concept. c. Choose a suitable measure of genetic distance given a data type and genetic model. d. To calculate distance between DNA sequences using MEGA software.
Geneticists may use specific mathematical formulae to adjust large recombination frequencies to account for the possibility of multiple crossovers, and thus get a better estimate of the actual distance between two loci.
relationships matrix helps in understanding genetic properties of the animal model. The numerator relationships are equal to twice the coancestry, and they express the proportion of additive genetic variance that two individuals have in common.
pairwise calculations, a genetic map of many loci on a chromosome can be produced (Figure 10-3). 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 ...
