I think that it is how the shop guppies are intensively bred and raised that is more of a problem then genetics,leaving them more vulnerable to infection,parasites and disease. Killifish and Livebearers have been kept and inbred for 30/40 years from a single collection and still going.
if genetics are to blame even buying from a reputable breeder will not help as these fish are probably more inbred to fix the strain
