TABLE 4.

Clusters of shared polymorphic sites (Stephens test)

Cluster	Nucleotide position	Deduced codons (majority/ minority)	Majority/ minority alleles	P
1	815–819	AGA GAA/AAT TCT	9:5	<0.0001
2	908, 910	ATT AAT/AAT TAT	8:6	<0.005
3	20	AG T/AA T	9:5	<0.05
	70	G AA/A AA
	120	CGT/CGC

Sites of the majority and minority motifs are shown in italics within their inferred codons. Synonymous sites within clusters are underlined. Positions of sites are assigned according to the overall sequence alignment.
