MCQ
Genetic erosion is due to:
  • A
    Deforestation.
  • B
    Shifting cultivation.
  • C
    Adoption of genetically uniform varieties.
  • D
    All of the above.

Answer

  1. All of the above.

Explanation:

Genetic erosion is a process whereby an already limited gene pool of an endangered species of plant or animal diminishes even more when individuals from the surviving population die off without getting a chance to meet and breed with others in their endangered low population.

Low genetic diversity in a population of wild animals and plants leads to a further diminishing gene pool, inbreeding and a weakening immune system and fast tracks that species towards eventual extinction.
