This supergene region not only allows insects to mimic each other, as in Heliconius, but also to mimic the soot blackened background of the industrial revolution - it's a gene that really packs an evolutionary punch," Professor Richard ffrench-Constant of the University of Exeter added.
Unlike the nearly immutable risk conferred by the supergenes, these polymorphisms raise the specter of cancer only in the presence of specific environmental hazards.
Whereas cancer-causing supergenes run in only a few families, polymorphisms are part of everyone's genetic heritage.
