Answer: Prevent self-pollination in the seed parent.
- A Prevent self-pollination in the seed parent
- B Increase the number of ovules
- C Speed up endosperm formation
- D Make the flower attractive to insects
Correct answer: A. Prevent self-pollination in the seed parent
Explanation: Emasculation removes the anthers before they mature so that the emasculated flower cannot self-pollinate during artificial hybridisation.
Double fertilisation in angiosperms: one male gamete fuses with the egg to form the diploid zygote (syngamy), while the second fuses with the two polar nuclei to form the triploid primary endosperm nucleus (triple fusion). Image: Triploid, CC BY 3.0, via Wikimedia Commons.
