Redundant Haplotypes doubt

[Betum]

Hi there! 

I come here because a doubt about Redundant Haplotypes and his repercussions.

I have been doing my thesis for the grade of Biologist about the Evolutionary Significant Units, this are populations of organism that were genetically isolated and have a diferent genetic variability. To make a delimitation of ESUs we indentificate reciprocal monophyly on a genetic tree, in this case whit COI and some of this ESUs have redundant haplotypes with some other locations.

¿ This redundant haplotypes make this reciprocal monophyly no viable?¿ This redundant haplotypes indicate a genetic relation?

I have this dudes because i read, that is very difficult to have the same two haplotypes frommutations or another mechanisms, and that make this ones good to make filognenetic reconstructions.  i not have literature about redundant haplotypes.

I'm not a native speaker, i hope my doubt was cleary explain.

I'm not sure if you're asking about technical problems of genome mapping, or about the evolutionary significance of genetic redundancy?

For the technical side, does this help? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4937319/

For the evolutionary significance, the simplistic answer is that redundancy increases the chances of survival if a chance mutation proves to be deleterious. A "back up plan" so to speak.
