Genomes are the complete set of DNA for all organisms in a particular species, whether it be an individual organism or a population.
Intact genomes are those that have not been transformed by random mutations. A mutation is any change in the genetic code that can be inherited by offspring, either directly or through a chromosome.
The term “intact genome” is used to describe a population of organisms whose genomes have not been altered by events such as radiation, mutagenesis, or transpositions.
