Deletion and point mutation rates in the line of descent.

<p>(A) Rate of genes deleted per accepted deletion event as a fraction of total genome size. These fractions were averaged for all fit runs with (red) and without (cyan) a WGD as well as a control set of runs that continued without environmental change (gray), and binned in 1000 generation intervals. In the inset, accepted deletion fractions are per generation instead of per event. (B) Accepted point mutation rates per generation as a fraction of total genome size. The fractions were averaged for all fit runs with (red) and without (cyan) a WGD as well as a control set of runs that continued without environmental change (gray), and binned in 1000 generation intervals.
