Medical Genetics Mutations are heritable changes in genetic material
Medical Genetics 1. Mutagens or Mutagenic Agents These are substances conditions and forms that significantly increase the frequency of mutations

Medical Genetics Mutations can occur at a spontaneous rate or a far greater ate when there is exposure to mutagenic agents
Medical Genetics Mutations can occur at a spontaneous rate, or a far greater rate when there is exposure to mutagenic agents
Medical Genetics Exposure to too high a level of mutagens can threaten the survival of a species; e. g,, frog species in the states of Washington and Oregon are facing extinction. This appears to be caused by reduced atmospheric ozone, and the resulting increased level of ultraviolet radiation
