Explanation:
Codominance.
Codominance occurs when, for example, a Dominant Blue color gene for a leaf crosses with a Dominant White color gene for a leaf. The genotype would be BW. This would result in, for example, a blue and white spotted leaf color. INCOMPLETE dominance occurs when both dominant alleles blend together, resulting in, eg, a pale blue color resulting from the blue and white colors mixing.
Reduce if, in your case, it means using less. Because that means you never have a need to do the others because nothing was ever “dirtied” For example like a plastic cup if you never drank out of it you can’t recycle it or reuse it or downsize it.
