  1. One thousand bases of quail mitochondrial DNA were downloaded to Geneious from the GenBank database. PCR primers were designed to amplify a conserved region from this sequence. Each primer was 20 bases long, and the 5` end of the forward primer (F) and reverse primer (R) starts from base position 33 and 865, respectively. A PCR master mixture for 23 reactions to analyse different bird samples was prepared.
