This study also studied the specifics about how the MHC genes are impacted. Almost 60 different populations of Guppy fish were studied and hundreds of immune variants were observed. These immune variants were classified as alleles, but there were also clusters of functional groups within those alleles classified as super types. The super types track the quick evolution of parasites and so they also have to be well-evolved. The evolution of such immune genes have been debated by scientists for years, however this study helps bring some clarity.
I think this study was important as it shows new understanding about the immune system, as well as helps clarifies fuzzy generalizations made. I believe more research should be done on this because the more information we can gain on the immune system the better. It is after all an incredible body system that helps keep organism alive.
