=+354 13. Numerical Methods count process Xt moves from state to state by randomly selecting two genes, which may coincide. The first gene dies, and the second gene reproduces a replacement. If the second gene is of type i, then its daughter gene is of type j with probability pij . The replacement times are independent and exponentially distributed with intensity λ.

Reformulate Moran’s model to proceed by reaction channels. What are the intensity and the increment of each channel?
