Selective Breeding

Selective breeding, also known as artificial selection, is a process where humans breed plants and animals for specific genetic traits. This practice has been ongoing for thousands of years, starting with the domestication of plants and animals, which laid the foundation for agriculture and civilization. The process involves selecting parents with desired traits and breeding them over generations to achieve the desired characteristics. However, inbreeding can lead to genetic risks, such as increased disease vulnerability. Modern advancements like genetic engineering offer faster alternatives by directly transplanting genes. Despite its benefits, selective breeding poses risks like reduced genetic diversity.
