Table 1. Enhancer haplotype library characteristics.

For each library of enhancer haplotypes, we list the number of distinct haplotypes, the number of tags with which those distinct haplotypes are associated in cis, the percentage of possible single nucleotide substitutions that are present in at least one haplotype, the percentage of possible pairs of positions where both positions contain mutations together in at least one haplotype, and the per-base mutation rate in each library.

Library	Number of haplotypes	Number of tags	% of possible substitutions in at least one haplotype	% of possible pairs of sites in at least one haplotype	Per-base mutation rate per haplotype (mean ± s.d.)
ALDOB	378,450	406,071	100% (777 of 777)	100% (33,411 of 33,411)	0.021 ± 0.010
ECR11	105,795	105,832	100% (1860 of 1860)	100% (191,890 of 191,890)	0.023 ± 0.006
LTV1 rep. 1	119,950	403,869	100% (906 of 906)	99.99% (45,449 of 45,451)	0.031 ± 0.010
LTV1 rep. 2	105,188	270,924	100% (906 of 906)	99.99% (45,449 of 45,451)	0.031 ± 0.010
