MCQ
Genetic erosion is due to:
- ADeforestation.
- BShifting cultivation.
- CAdoption of genetically uniform varieties.
- DAll 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.
