Genetic polymorphism

Genetic polymorphism refers to the natural variation in DNA sequences among individuals within a population. These variations create different versions, or alleles, of genes, which can influence physical traits, health, and how people respond to medications. Polymorphisms are common; most humans carry many of them, contributing to diversity in characteristics like eye color or disease resistance. They are part of what makes each person genetically unique and play a significant role in evolution and population genetics.
