Definition of polymorphism in English:
1.1 Biology The occurrence of different forms among the members of a population or colony, or in the life cycle of an individual organism.
- Many of the 5000 or so bryozoan species exhibit polymorphism.
- In the subclass Hexacorallia, polymorphism of polyps in colonies is unknown, so for this group, variation in life cycles simply involves fission.
- Examples of the concept include Integration and polymorphism: degree of autonomy of individual versus integration of specialized individuals, relative degrees of fitness (Boardman and Cheetham, 1973; Schopf, 1973; Bates and Kirk, 1985; Pitelka and Ashmun, 1985; Mackie, 1986).
1.2 Genetics The presence of genetic variation within a population, upon which natural selection can operate.
- Double reduction may play a significant role in plant evolution and the maintenance of genetic polymorphism in natural populations.
- A common goal of population genetic investigations is to explain the fate of genetic polymorphism within a species.
- Future clinical trials may be aimed at specific patient populations determined by genetic polymorphism and other risk factors.
1.3 Biochemistry The occurrence of a number of alternative forms within a section of a nucleic acid or protein molecule.
- To analyze sequences for neutrality, we performed tests based on protein polymorphism only.
- Histograms of allelic frequencies revealed strikingly different patterns of polymorphism among loci.
- The large number of loci investigated in this study allowed us to search for possible causes of different levels of polymorphism among loci.
1.4 Computing A feature of a programming language that allows routines to use variables of different types at different times.
- Late binding in addition to data types provides a needed aspect to allow polymorphism or the choosing of an object's method implementation at run-time.
- RMI uses object serialization to marshal and unmarshal parameters and does not truncate types, supporting true object-oriented polymorphism.
- The doubling-up of parentheses in the way Verity describes is nothing more or less than an early form of polymorphism, as functions can also be seen as virtual arrays of infinite values.
- Example sentences
- This last approach may under-represent evolutionary steps within those polymorphic taxa.
- There are 4 common polymorphic forms of factor XIII that differ among ethnic groups.
- This is a reasonable assumption because of the low frequency of polymorphic sites in the analyzed set of sequences.
- Example sentences
- In short, I can't decide whether or not I'm a congenital liberal, who found a vent to come out through, or a polymorphous soul which took on the first identity it found to be coherent.
- All manner of mouth noise, acoustic instruments and polymorphous percussion make up its rainbow plumage, essential during mating season.
- The polymorphous nature of identity and the choices we can make about who we are at any given time are some of the great liberations of our age.
