A model of this phenomenon that uses a tridiagonal transition matrix and has absorbing states at 0 and N is the Moran model, which adds timesteps to a model that assumes no generational overlap. This phenomenon is dominant in systems whose Tajima's D is equal to zero. When this is the only phenomenon acting, the time to fixation is equal to four times n sub e. A theory which posits that most instances of fixation are actually due to this phenomenon was developed by (*) Motoo Kimura and is called neutral theory. Wright and Fisher developed an early model of this process, which is more powerful for smaller populations and occurs due to random sampling. Examples of this effect include the bottleneck effect and the founder effect. For 10 points, name this phenomenon in which alleles change ove
