Web25. Distance Matrices. It is often common in population genetics to estimate pairwise distance matrices representing difference in quantities such as spatial location, phenological overlap, genetic differentiation, ecological separation. Dealing with distances is fraught with problems and continues to be an area of active research. WebA very short distance is, effectively, a very small "target" for crossover events, meaning that few such events will take place (as compared to the number of events between two further-apart genes). Thanks to this relationship, we can use the frequency of recombination events …

WebDistances were estimated using pairwise γ genetic distances (a=0.50) and the Tamura–Nei model of nucleotide substitution (Tamura and Nei, 1993); the tree is midpoint rooted. Distances are listed above branches, and values for 1000 bootstrap replications ( Felsenstein, 1985 ) are below branches.
