also "decreased rate of spontaneous mutation"
Parentage for this may be "rate of mutation phenotype" under the "genomic integrity" parent
this would have similar parentage to the "mutation rate" term but again, there is some debate as to the ultimate parentage for these types of terms.
These terms were added to the ontology as children of the 'genetic material phenotype' branch:
OMP:0005048 ! mutation frequency phenotype
[–] OMP:0006071 ! altered mutation frequency (2)
[ ] OMP:0005068 ! increased mutation frequency
[ ] OMP:0005069 ! decreased mutation frequency
