Answer: A plant produced by fusion of protoplasts from two different plant species.
- A A hybrid produced by the sexual fusion of gametes from two distinct species
- B A plant produced by fusion of protoplasts from two different plant species
- C A plant that has undergone a deliberate doubling of its chromosome number
- D A hybrid produced through repeated backcrossing to a single parental line
Correct answer: B. A plant produced by fusion of protoplasts from two different plant species
Explanation: Somatic hybrids are plants produced by fusing protoplasts (cells with cell walls removed) from two different plant species, combining their genomes.
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.
