Question

The original population of brown spotted deer declined drastically after their forest habitat was flooded. After frantic efforts over three decades by the forest authorities to revive the dwindling population, it did bounce back. Now the deer population is as huge as it was three decades ago, but it shows a decreased amount of genetic variations. Which factor could be responsible for this microevolution?

Answer 1

it's the bottleneck effect, answer a

Step-by-step explanation:

Answer 2

CHOICES:
a. bottleneck effect
b. natural selection
c. founder effect
d. gene flow

The above scenario is known as the A.) BOTTLENECK EFFECT.

Bottleneck effect occurs when a drastic event resulted to a great reduction of a population wherein the remaining or surviving animals rarely represent the actual genetic makeup of the original or initial population. The surviving animals only leaves a smaller variation of its genetic makeup.
