Mutation vs. Polymorphism

Mutationnoun

Any alteration or change.

Mutationnoun

(genetics) Any heritable change of the base-pair sequence of genetic material.

Mutationnoun

A mutant.

Mutationnoun

(linguistics) An alteration a particular sound of a word, especially the initial consonant, which is triggered by the word's morphological or syntactic context and not by its phonological context.

Mutationnoun

A group of thrushes.

Mutationnoun

Change; alteration, either in form or qualities.

Mutationnoun

Gradual definitely tending variation, such as may be observed in a group of organisms in the fossils of successive geological levels.

Mutationnoun

As now employed (first by de Vries), a cellular process resulting in a sudden inheritable variation (the offspring differing from its parents in some well-marked character or characters) as distinguished from a gradual variation in which the new characters become fully developed only in the course of many generations. The occurrence of mutations, the selection of strains carrying mutations permitting enhanced survival under prevailing conditions, and the mechanism of hereditary of the characters so appearing, are well-established facts; whether and to what extent the mutation process has played the most important part in the evolution of the existing species and other groups of organisms is an unresolved question.

Mutationnoun

a variant strain of an organism in which the hereditary variant property is caused by a mutation{3}.

Mutationnoun

(biology) an organism that has characteristics resulting from chromosomal alteration

Mutationnoun

(genetics) any event that changes genetic structure; any alteration in the inherited nucleic acid sequence of the genotype of an organism

Mutationnoun

a change or alteration in form or qualities

Mutation

In biology, a mutation is an alteration in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements.Mutations may or may not produce detectable changes in the observable characteristics (phenotype) of an organism.

Polymorphismnoun

The ability to assume different forms or shapes.

Polymorphismnoun

(biology) The coexistence, in the same locality, of two or more distinct forms independent of sex, not connected by intermediate gradations, but produced from common parents.

Polymorphismnoun

(object-oriented programming) The feature pertaining to the dynamic treatment of data elements based on their type, allowing for an instance of a method to have several definitions. en

Polymorphismnoun

The property of certain typed formal systems of allowing for the use of type variables and binders/quantifiers over those type variables; likewise, the property of certain expressions (within such typed formal systems) of making use of at least one such typed variable.

Polymorphismnoun

(crystallography) The ability of a solid material to exist in more than one form or crystal structure; pleomorphism.

Polymorphismnoun

(genetics) The regular existence of two or more different genotypes within a given species or population; also, variability of amino acid sequences within a gene's protein.

Polymorphismnoun

Same as Pleomorphism.

Polymorphismnoun

The capability of assuming different forms; the capability of widely varying in form.

Polymorphismnoun

(chemistry) the existence of different kinds of crystal of the same chemical compound

Polymorphismnoun

(biology) the existence of two or more forms of individuals within the same animal species (independent of sex differences)
