Figure B2:

Normalized mean coalescence times for autosomal double-first-cousin mating. Coalescence times are plotted as a function of the number of mating pairs (N) and the proportion of mating pairs that are double-first-cousin pairs (c₁). (A) $\mathbb{E}\left[T_f\right]/(4N)$, Eq. 12. (B) $\mathbb{E}\left[V_{mf}\right]/(4N)$, Eq. 14. The dashed lines represent the maximal reduction due to consanguinity, c = 1: $\frac{1}{2}$ in (A) and $\frac{5}{8}$ in (B).
