During artificial hybridization experiments in pea plants, emasculation refers to the removal of:

  1. A
    Stigma from the female parent before flower opening
  2. B
    Anthers from the female parent flower before dehiscence
  3. C
    Carpels from the male parent flower
  4. D
    Petals to expose the reproductive organs

Correct answer · Option B

Anthers from the female parent flower before dehiscence

Explanation

Emasculation is the process of removing anthers from the flower bud of the female parent before they dehisce to prevent unwanted self-pollination.
