Figure 8From: A minimal descriptor of an ancestral recombinations graph(a) Non-resolvable node v (b) t-coalescent node v The arrows point to the junctions in the segment. In each of the two there is an increase in the number of junctions from the descendants to the coalescing vertex v. (a) A non-resolvable node and the coalescence of two descendants has produced an additional junction, shown by a cyan arrow. (b) A t-coalescent node and the coalescence of the eight descendants. The four coalescences give rise to three junctions.Back to article page
