Figure 1

Illustration of the instantaneous rates for an array of length 3. Leader-proximal end is on the left. The arrows display the allowed transitions for the fragment loss model. Deletions of length two are are displayed in red, deletions of length three in green. For the independent loss model, only the black arrows are allowed transitions. For the unordered model, the transition with rate λ results in either 4-3-2-1, 3-4-2-1, 3-2-4-1 or 3-2-1-4 with uniform probabilities.
