Which of the following characterizes dynamic equilibrium? (Check as many as apply)

1. The forward and backward mutation rates must be zero.

2. It always occurs in a single generation.

3. There is no net change in the distribution of alleles.

4. The number of forward and backward mutations must be equal.

Solution

States of dynamic Equilibrium;

1. The forward and backward mutation rates must be zero.

Explanation: Although mutation is a linear process, yet if the mutations balance each other, they are in dynamic euilibrium.The rates must be equal and opposite. However, the concentrations may not be equal. Thus number of forward and backward mutations reactions may or may not be equal.

Mutations are not transmitted equally from one generation to another beacuse fowrward and backward mutations may counteract on each other. Dynamic equilibrium acts in a population regardless of generations.

Also, dynamic equilibrium is not affected by distribution of alleles, as alleles have an average affect in a given environment. \'There is no net change in distribution of alleles\' ...is an assumption of Hardy-Weinberg\'s equilibrium.
