Here's why:
* Selective breeding focuses on specific traits: Breeders select for desired characteristics, often leading to a narrowing of the gene pool. This means the resulting organisms have a more limited range of genes and are more susceptible to diseases or environmental changes.
* Natural organisms have broader genetic variation: Organisms that have evolved naturally have a much wider range of genes, allowing for greater adaptability and resilience. They are less likely to be wiped out by disease or sudden environmental changes.
This is why maintaining genetic diversity is so crucial in conservation efforts. It helps populations adapt and survive in the long term.
