Polymorphisms can cause variations in gene function and expression, leading to differences in traits among individuals, such as susceptibility to diseases, response to medications, and other phenotypic characteristics. These genetic variations can also contribute to evolutionary processes by introducing diversity within populations. Additionally, polymorphisms may influence the outcome of complex traits and can be important in fields like pharmacogenomics and personalized medicine.

Variations in specific nucleotides that are linked to human diseases are called single nucleotide polymorphisms (SNPs). These variations occur when a single nucleotide in the DNA sequence is altered, which can potentially affect gene function and increase the risk of developing certain diseases.
Single nucleotide polymorphisms:SNP is a DNA sequence variation occurring when a single nucleotide - A, T, C or G - in the genome.

Scientists use genetic markers such as microsatellites or single nucleotide polymorphisms (SNPs) in DNA to determine individual identities of organisms within the same species. These markers show variations in DNA sequences that can be used to distinguish one individual from another.
