Polymorphism definition in genetics

WebGenetic polymorphism can also be defined as the occurrence in the same population of two or more alleles at one locus, each with appreciable frequency (Cavalli-Sforza and Bodmer, 1971). A formal definition, such as the above, based on the frequency of genes that are found in a population is likely to be the most satisfactory. WebPolymorphisms. A polymorphism is the occurrence of two or more clearly different phenotypes within the same population of a species. Whereas alleles are the individual components of a gene, polymorphisms are the individual components of a traits. Consequently, polymorphisms reflect the involvement of more than one allele for any …

A polymorphism can be any sequence difference. Examples include: • Single nucleotide polymorphisms (SNPs) are a single nucleotide changes that happen in the genome in a particular location. The single nucleotide polymorphism is the most common form of genetic variation. • Small-scale insertions/deletions (Indels) consist of insertions or deletions of bases in DNA.
