Power to infer Neandertal ancestry. a, Simulated power to infer Neandertal ancestry as a function of the effective population size. b, Power to infer Neandertal ancestry on chromosome X versus the autosomes. Recall is computed at a precision of 90%. Standard errors are estimated by a block jackknife with 100 blocks.

a
Effective population size	Recall
2500	0.552 ± 0.009
5000	0.506 ± 0.009
7500	0.430 ± 0.006
10000	0.384 ± 0.006

	Recall
Autosomes	0.384 ± 0.006
X	0.495 ± 0.009
