What is disturbance in Hardy-Weinberg genetic equilibrium indicative of. Explain how it is caused.

Explanation

### Step-by-Step Solution:

1. **Understanding Hardy-Weinberg Equilibrium**:
- The Hardy-Weinberg equilibrium is a principle that describes a stable genetic state in a population where allele frequencies remain constant from generation to generation, provided that certain conditions are met (no mutation, migration, selection, or genetic drift).

2. **Identifying Disturbance**:
- A disturbance in this equilibrium indicates that the genetic composition of the population is changing. This can be observed when the sum of the frequencies of the genotypes (homozygous dominant, homozygous recessive, and heterozygous) does not equal 1.
