A plant breeder crossed an onion with a white bulb (RRXX) to another with red bulbs (rrxx).
All progenies expressed white bulbs and crossed again. Among the 448 progenies screened,
84 plants appeared to have green bulbs. If the white coloration of the bulbs is a result of
dominant epistasis, how many plants express red bulbs?
