This study used polymerase chain reaction and direct sequencing method to infer the taxonomic relationship between Golden Pheasant(Chrysolophus pictus) and Lady Amherst's Pheasant(C.amherstiae).A total of 468 nucleotides of the mitochondrial DNA control-region gene were sequenced.There are 26 variable positions,with 19 transitions,6 transversions and 1 deletion.The sequence variation was very significantly different between Golden Pheasant and Lady Amherst's Pheasant.What's more,the nucleotide composition of A,T and C were noted different between the two pheasants.Genetic distance between Golden Pheasant and Lady Amherst's Pheasant was 0.035±0.008 based on Kimura-2-parameter's method.The divergence time between Golden Pheasant and Lady Amherst's Pheasant was((1.75±0.40)) Myr using the rate of 2% mtDNA sequence divergence/ 1Myr.This result suorted that Golden Pheasant and Lady Amherst's Pheasant were two distinct species.The ancestors of Golden Pheasant and Lady Amherst's Pheasant could have evolved allopatrically in the southern of Qinling Mountain and the Hengduan Mountain.
