Two Populations Experience Equally Severe Bottlenecks,reducing Each to One-Tenth of Its

question 11

Essay

Two populations experience equally severe bottlenecks,reducing each to one-tenth of its original size.One population is in the bottleneck for one generation,and the other is in the bottleneck for five generations.You assess the heterozygosity of both populations after they have been restored to their prebottleneck size.What do you expect to find,and why?

Definitions:

Depolarization

A decrease in membrane potential that makes the interior of a cell less negative compared to the outside, crucial for nerve impulse transmission and muscle contractions.

Repolarization

The process by which a cell's membrane potential returns to its resting state after depolarization.

Afterpotential

Afterpotential represents the change in membrane potential that follows an action potential in nerve cells, affecting the cell's responsiveness to subsequent stimuli.

Threshold

The point or level at which a stimulus is of sufficient intensity to begin to produce an effect.
