Examples of distance computations Part (a) shows the computation of normalized distance between two pairs of segments. The distance is the number of positions with different nucleotides divided by the length of the sequence. Part (b) shows the new normalized distance using information from the four segments. This distance is computed by evaluating the number of mutations that precede speciation, assuming that the speciation event followed the duplication event. (See Methods for the details of the computation).
