Problem: Eggplant fruit color may be dark purple, violet, or white. Crosses between purple and white eggplants always produce violet eggplant progeny. However, the crossing of these violet eggplants gives the following progeny: 110 violet, 54 purple, and 56 white eggplants. What is the genetic basis of fruit colors in eggplants?
