• Polymorphism is a form of genetic variation in which distinct nucleotide sequence can exist at different sites in a DNA molecule.
• This heritable mutation is observed at a high frequency in a population.
• This results in accumulation of various mutations in a population, leading to variation and polymorphism in the population.
• This plays a very important role in the process of evolution and speciation.
