The Hardy-Weinberg Principle explains how the frequencies of genes in a population can stay the same if there are no outside influences.
However, in real life, things are often different because of various challenges:
Genetic Drift: This happens when random changes affect gene frequencies, especially in small groups. This can upset the balance.
Mutation: New genes can appear, changing how often different genes are found in the population.
Natural Selection: Some genes can help individuals survive better or have more babies. This can change how often certain genes are seen.
Gene Flow: When people or animals move into a new area, they can bring new genes with them, which alters the gene frequencies.
To keep the Hardy-Weinberg balance, populations need to be large, isolated, and without changes from mutations, natural selection, or migration. But in nature, this is almost impossible to achieve.
