Genetic Diversity
Definition
Genetic diversity refers to the variety of genes within a population or species. It is crucial for the long-term survival and adaptation of organisms because it allows for greater resilience against environmental changes.
Analogy
Imagine a toolbox filled with different tools. Just as having various tools helps you tackle different tasks effectively, genetic diversity provides a population with a range of traits that can help them overcome challenges in their environment.
