  Two pink coloured flowers on crossing resulted in 1 red, 2 pink and 1white flower progeny. The nature of the cross will be (a) double fertilization   (b) self pollination           (c) cross fertilization       (d) no fertilization

Answer:

                  (c) The nature of the cross will be cross fertilization. Fertilizing a plant using pollen from another plant of the same species is cross-fertilization. Double fertilization is a complex fertilization mechanism of flowering plants. It involves fusion of a male and female gamete. Self-pollination is a form of pollination that occurs in a flower that has both stamen and carpel.
