Table 3. The numbers (and percentage) of positively selected sites of ostrich TLR4.

TLR4 domains	SLAC	FEL	REL	MEME	Either (>1) *	Either*(>3) *
ECD	10 (91%)	20 (91%)	27 (84%)	54 (92%)	72 (90%)	13 (87%)
TM	1 (9%)	1 (5%)	3 (9%)	2 (3%)	5 (6%)	1 (7%)
ICD	0 (0%)	1 (5%)	2 (6%)	3 (5%)	3 (4%)	1 (7%)

ECD, extracellular domain; TM, transmembrane domain; ICD, intracellular domain.

*” Either (>1)” and” Either (>3)” indicate the sites which were detected using at least one or three methods of SLAC, FEL, REL and MEME.
