Recombination analysis of penA-232.001 gene. An alignment of N. gonorrhoeae and commensal Neisseria species penA sequences were analysed using the RDP4 software. The X-axis and Y-axis represent the position in alignment and pairwise identity, respectively. The yellow line represents the pairwise of N. perflava as a major parent, and N. polysaccharea as a minor parent. The green line represents the pairwise of N. perflava as a major parent, and N. gonorrhoeae as a recombinant. The purple line represents the pairwise of N. polysaccharea as a minor parent, and N. gonorrhoeae as a recombinant
