Current Question (ID: 13167)

Question:
Self-incompatibility: I. Is a device to prevent inbreeding II. Provides a biochemical block to self-fertilization. III. Ensures cross-fertilization. IV. Is governed by pollen-pistil interaction V. Is governed by series of multiple alleles. VI. Prevents self pollen (from the same flower or other flowers of the same plant) from fertilizing the ovules inhibiting pollen germination or pollen tube growth in the pistil.
Options:
  • 1. All are correct
  • 2. All are wrong
  • 3. Only I, II, III are correct
  • 4. IV and V are wrong
Solution:
Self-incompatibility prevents inbreeding. This is a genetic mechanism and prevents self-pollen (from the same flower or other flowers of the same plant) from fertilising the ovules by inhibiting pollen germination or pollen tube growth in the pistil.
