Figure 7.

Patterns of situation changes that include relatively small numbers (up to three) of events. Three kinds of divergence patterns (a, b, c, d; e–h) of the three genera (Nomascus, Symphalangus and Hylobates) are considered. The signs in parentheses show the relative strength of FISH signals in the telomere region (+ and ++) and absence of signals (0). Four kinds of transitions were defined as shown at the bottom, and designated with their first letters (underlined). The letters are placed on branches where they are assumed to have occurred in each branching pattern.
