Table 2

Sequence statistics and nucleotide pair frequency analysis of sequences representing chloroplast rbcL, and matK loci of accessions of Chenopodium investigated in the present study.

Gene	Sequence statistics					Nucleotide pair frequencies
	Mean length (pb)	CS	VS (%)	PIS	SS	ii	si	sv	R
matK	646	260	56.96	77	288	519	13	18	0.69
rbcL	1344	800	32.88	85	352	860	19	23	0.82
matK + rbcL	2226	453	72.46	402	1175	1360	52	81	0.65

CS: conserved sites; VS (%): variable site percentage; PIS: parsimony-informative sites; SS: singleton sites; ii: identical pairs; si: transitional pairs; sv: transversional pairs; R: si/sv.
