Why is there no term for abolished X?
PATO has a quality named "abolished". We consider abolished to be the limit case of decreased. Use decreased X.
Why would you describe a complete loss as decreased X, which a child of X positive?
Example:
- decreased motility is a child of motile
- decreased catalase activity is a child of catalase activity
Why not use the non-X term, e.g. nonmotile or catalase negative
We use terms like nonmotile and catalase negative to annotate properties of a species, while decreased motility or decreased catalase activity are used for mutants where there is less of X than in the reference strain (wt or a parent), which is motile and catalase positive.
