Distinguishing features among the terms gene allele polymorphism and mutation
Gene
the nucleic acid sequence that carries the information to build a particular protein
Alleles
any of the alternative forms (sequence variants) of a gene
Polymorphism
multiple alleles at any locus that exist across a population. A nondisease-causing genetic variant is termed a benign polymorphism.
Mutation
change in DNA sequence (with or without detectable effects)
