Number of human and chimpanzee INDELs associated with noninterspersed sequences

	Human gaps			Chimpanzee gaps
Noninterspersed sequence subclass	CIs	HDs	CIs + HDs	HIs	CDs	HIs + CDs	Total insertions (CIs + HIs)	Total deletions (CDs + HDs)	Total INDELs (CIs + HIs + CDs + HDs)
TRs	720	546	1,266	814	520	1,334	1,534	1,066	2,600
USs	1,156	1,767	2,923	1,145	1,267	2,412	2,301	3,034	5,335
Total	1,876	2,313	4,189	1,959	1,787	3,746	3,835	4,100	7,935

CD = chimpanzee deletion; CI = chimpanzee insertion; HD = human deletion; HI = human insertion; INDEL = insertion and deletion; TR = tandem repeat; US = unique sequence. Using Rhesus macaque as an out-group, we characterized INDEL variation as CDs, CIs, HDs or HIs.
