Somaclonal variation refers to:

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.

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.
