Explain the Hardy-Weinberg principle of equilibrium theory.

Hardy-Weinberg principle of equilibrium, is a statistical measure of populations under ideal conditions, and demonstrates whether or not a population is in genetic equilibrium.

Explanation:

That a population is in equilibrium means that the frequencies of the different genotypes, present in it, remain constant throughout the generations.

This only applies to an ideal population and fulfills the following statements:

- An infinitely large population

- Individuals are discrete (individuals reproduce only once)

- Crossing is always random (no selection)

- No inbreeding (crosses between related individuals)

In view of this, if a population is in equilibrium the frequencies P, H and Q will remind constant from one generation to the next.

Otherwise, the population is not in equilibrium.
