Text solutionVerified

Self-incompatibility is a condition where pollen is not able to fertilize the same flower or other flowers on the same plant due to inhibition of the growth of the pollen tube in the stigma and style, thereby preventing delivery of male gametes to the ovules. The absence of fusion of male and female gamete leads to no seed formation in these plants.
