We can test this by simulating several populations with initial size $N_0=20$ and averaging the time they take to reach $N=10$. Set the simulation to: | We can test this by simulating several populations with initial size $N_0=20$ and averaging the time they take to reach $N=10$. Set the simulation to: | ||

The graph will be covered with lots of lines, but we are interested in the value of //Halving time//. Is it near the theoretical value? Now change the population initial size to 80, keeping the other options unchanged and run the simulation again. | The graph will be covered with lots of lines, but we are interested in the value of //Halving time//.
