Table 1

Single-nucleotide polymorphic sites observed in the study.

Markers	Position	HO	HE	Allele change
SNP1	91^st	0.34	0.28	A > T
SNP2	107^th	0.34	0.32	C > G
SNP3	113^th	0.34	0.38	C > T
SNP4	194^th	0.28	0.30	G > A
SNP5	231^st	0.31	0.37	T > C

H_O: observed heterozygosity; H_E: expected heterozygosity. Position is the polymorphic site corresponding to 1 to 284 positions along the amplified product length from 5′ to 3′.
