• the observed sweep was mapped to a narrow region of ph-p containing several regulatory elements that are absent in ph-d
• this indicates that strong positive selection had been driving the functional divergence of these gene duplicates
• to my knowledge, this is the first case of neofunctionalization driven by positive selection in the presence of gene conversion
