Answer: Variation produced in tissue culture-derived plants.
- A Variation due to gamma ray mutation
- B Variation produced in tissue culture-derived plants
- C Variation due to polyploidy induction
- D Variation between different species of somatic cells
Correct answer: B. Variation produced in tissue culture-derived plants
Explanation: Somaclonal variation is the genetic variation observed in plants regenerated from somatic cells in tissue culture, often useful in crop improvement.
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.
