Options
- ATwice the number of progeny plants would bear violet fruits as compared to purple fruits.
- B75 % of the progeny plants would produce purple fruits.
- C25 % of the progeny would bear white fruits while the remaining would bear violet fruits.
- DEqual proportion of progeny would bear purple and violet fruits.
