Gene polymorphism - Wikipedia
WEBGenes which control hair colour are polymorphic. A gene is said to be polymorphic if more than one allele occupies that gene's locus within a population. [1] In addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic.
Polymorphism - National Human Genome Research Institute
WEB4 days ago · Polymorphism, as related to genomics, refers to the presence of two or more variant forms of a specific DNA sequence that can occur among different individuals or populations. The most common type of polymorphism involves variation at a single nucleotide (also called a single-nucleotide polymorphism, or SNP).

Genetic Polymorphism - an overview | ScienceDirect Topics
WEBGenetic polymorphism occurs as structural changes, including nucleotide substitution, complete gene deletion, gene duplication, and genetic translocation where portions of similar genes are combined creating a new gene hybrid.
Polymorphism (biology) - Wikipedia
WEBPut simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'.
Gene Polymorphism - an overview | ScienceDirect Topics
WEBGene polymorphisms are defined by the presence of multiple alleles for a given gene due to alterations in the nucleotide sequence, in which the different variants are present in at least 1% of the population.
