WebThe effect of migration on genetic distance has been studied with a finite island model for the following two cases: constant migration rate and decreasing migration rate. Results based on the assumption that migration rate decreases with time are very different from those based on the assumption of constant migration rate. Numerical results indicate that … WebNov 16, 2024 · In such model, a migrant could be an individual that actually come back to the same population. So, the probability of really migrating is $\frac{m (d-1)}{d}$ and assuming equal migration rate among all populations, the probability to migrate to a given population is $\frac{m}{d-1}$.
