2.5.2 Inference of recombination:
Recombination can influence the outcomes of selection, we first tested
recombination. Analyses were implemented for the nucleotide alignment of
exon 3 in the Recombination
Detection Program version 4 (RDP4). Several method, including RDP
[33], GENECONV [34], Chimaera [35], MaxChi [36],
BootScan [33], SiScan [37], and 3Seq [38], were used to
detect recombination events. In
addition, the online GARD tool, provided by the Datamonkey webserver
(http://www.datamonkey.org/), was used for recombination signals
assessment [39].
