B. Incomplete Dominance
In some situations, there is neither a dominant nor recessive gene. For ex, a RR (red) flower and WW (white) flower might lead to RW (pink). The latter case is one where there is less red (when compared to RR) rather than the red dominating the white. Thus it is a decrease in "redness" that results in RW.
