 The output agrees with $f = 1/16$.
 
 ### 3. Realised inbreeding (**ibdsim2**)
-For any particular child of first cousins, the actual fraction of the genome (except X & Y) that is autozygous is called the *realised inbreeding* coefficient, denoted $f_R$. Clearly, the expected value of $f_R$ is the pedigree-based coefficient $f$ calculated above, but there is in fact substantial variance.

 We can simulate the distribution of $f_R$ with the **ibdsim2** package. Since this is not a core package we must load it separately.
