What is the purpose of bagging in plant hybridization?

Answer: To prevent unwanted cross-pollination after emasculation.

  • A To physically shield the flower from damage by insect pests
  • B To prevent unwanted cross-pollination after emasculation
  • C To increase the overall rate of fertilization within the flower
  • D To induce chromosome doubling (polyploidy) within the flower

Correct answer: B. To prevent unwanted cross-pollination after emasculation

Explanation: Bagging involves covering emasculated flowers with paper bags to prevent contamination from unwanted pollen until artificial pollination is performed.

Composite Fish Culture: Niches in One PondCatla (surface feeder)Rohu (middle feeder)Mrigal/Common carp (bottom feeder)

Different fish species occupy different feeding depths in the same pond without competing for food: Catla feeds near the surface, Rohu in the middle zone, and Mrigal or common carp at the bottom - letting a single pond support far more total fish than one species alone.
