Table 4. Amino acid sites under positive selection.

Site	Ovar-DRA*0201	Substitution	P value
6	M	V	0.963
11	G	E	0.969
12	I	F	0.989
14	V	L	0.983
72	V	I	0.970
74	T	I	0.979
76	Y	R	0.995
152	S	P	0.976
168	C	W	0.965
169	S	G	0.982

Numbering of amino acid sites under selection is as shown in Figure 2. P = the probability of the ratio of nonsynonymous to synonymous substitutions at each site being greater than one.
