| spontaneous |
A mutation discovered among the descendants of a mouse whose germ cells were not exposed to a chemical or physical mutagen. Additionally, certain mutants that had a mutagen-treated parent or ancestor have been concluded to be of spontaneous origin if the germ-cell stage being sampled is not that which has been exposed, or if the mode of inheritance cannot account for appearance of the mutant. These special circumstances for certain specific alleles are explained under Additional Remarks.
