Genetic polymorphism refers to the existence of variations in the DNA sequence between different individuals within a specific population. Some of the synonyms for this term includes gene variation, genetic diversity, genetic variability, genetic variation, and allelic diversity. These terms refer to the fact that different individuals in a population can have different alleles, or versions of the same gene, that lead to specific genetic traits and phenotypic outcomes. Genetic polymorphism is an important concept in genetics and plays a crucial role in evolution, disease susceptibility, and pharmacogenomics. By understanding the genetic variability in populations, researchers can develop new treatments and therapies that better target genetic variations among individuals.
