Changes in gamete frequency

We can use this table as we did earlier to calculate the frequency of each gamete in the next generation. Specifically,

$$\begin{eqnarray*} x_{11}' &=& x_{11}^2 + x_{11}x_{12} + x_{11}x_{21} + (1-r)x_{... ... x_{21}' &=& x_{21} + rD \\ x_{22}' &=& x_{22} - rD \quad . \end{eqnarray*}$$
