polymorphic genes
Polymorphic genes are variations of a gene found within a population. These variations can lead to different traits, like eye color or disease susceptibility. Think of it as having several options for a recipe: each option can create a slightly different dish. In biology, these variations contribute to genetic diversity, allowing populations to adapt to changes in the environment. Polymorphism is essential for evolution, as it provides the raw material for natural selection, where certain traits may be favored over others, enhancing survival and reproduction.
