3.5 Recombination analysis
RDP4 software was used to analyze recombination events. Analysis showed
that Colombia-2016 (KX857728.1) could be a potential major parent while
HB-CH-2016 (KX377924.1) could be a potential minor parent. Our results
provided strong statistical support for a recombination event involving
CH-GX-01-2019 (P <0.01). SimPlot analysis revealed the
existence of breakpoints that separated the genome of CH-GX-01-2019 into
two fragments; one fragment originated from Colombia-2016 (1-1903 nt)
while the another fragment originated from HB-CH-2016 (1903-7303 nt)(Fig. 4) .
