If pollen from a mango flower is transferred to the stigma of a guava flower, it is unlikely to result in successful fertilization. While both mango and guava are in the same plant family, they are not known to be cross-compatible for pollination. In most cases, for successful fertilization to occur, pollen should be transferred between flowers of the same species or a closely related species.
