A gene pool refers to the complete set of genetic information within a population of a particular species. It includes all the different alleles (variations of genes) present in that population, which can influence traits such as color, size, and resistance to diseases. The diversity of a gene pool is crucial for the adaptability and survival of a species over time. When a population has a rich gene pool, it is more resilient to environmental changes and diseases. Conversely, a limited gene pool can lead to inbreeding and a higher risk of genetic disorders. Conservation efforts often aim to maintain or restore the gene pool of endangered species like tigers or bald eagles.
