Hello,
I am interested to look at regions that experienced selective sweep in both subgenomes. I have identified a set of regions that are under selection in both subgenomes
Example, identified regions from subgenome A

Is it possible to find synteny between two subgenomes using the two subsets of the annotation file? Is there is any specific tool can do this?
It came to my mind to use command line where I can just look for common genomics regions "common start and end" between the two subset files, I end up having no common regions, as they're unique for each file. However, I don't think this is the correct way to do it. I think using synteny could be the ideal way.
