Expected coalescent times with different reproductive systems. The population size for all plots is
N = 10,000. (A) Expected mean coalescent time according to in coalescent time units as a function of sex σ. The blue line represents between-individual mean coalescent time
, and the red line is within-individual mean coalescent time
. The vertical line represents
(
), and the horizontal solid lines show the predicted mean coalescent times for this value (
;
on the coalescent timescale), whereas the horizontal dashed line shows
. (B and C) Expected coalescent time if selfing is also included, according to . Line colors are the same as in A, with (B) σ = 1 or (C) σ = 1/
N (
).
