What is phenotypic polymorphism?
Phenotypic polymorphism is a consequence of developmental plasticity, in which the trajectories of developing organisms diverge under the influence of cues. Both types of cues can help a developing organism to fit its phenotype to selective circumstances.
What does polymorphism mean in biology?
​Polymorphism = Polymorphism involves one of two or more variants of a particular DNA sequence. The most common type of polymorphism involves variation at a single base pair. Polymorphisms can also be much larger in size and involve long stretches of DNA.
What are the types of polymorphism in biology?
Various types of polymorphisms include:
- single nucleotide polymorphisms (SNPs)
- small-scale insertions/deletions.
- polymorphic repetitive elements.
- microsatellite variation.
Does polymorphism affect phenotype?
These findings demonstrate that although LHCGR polymorphisms alone may have only marginal effects on the phenotype, in combination with other polymorphisms their impact could be significant.
What polymorphism means?
Polymorphic: The combined term refers to the existence of more than one form of traits in a species. When we combine the two terms as polymorphism, it indicates the presence of a gene with multiple variations in polymorphic traits.
Which one is the best definition of polymorphism?
In object-oriented programming, polymorphism (from the Greek meaning “having multiple forms”) is the characteristic of being able to assign a different meaning or usage to something in different contexts – specifically, to allow an entity such as a variable, a function, or an object to have more than one form.
What is the importance of polymorphism in biology?
Polymorphism is common in nature; it is related to biodiversity, genetic variation, and adaptation. Polymorphism usually functions to retain variety of form in a population living in a varied environment. The most common example is sexual dimorphism, which occurs in many organisms.
What is polymorphism Ncert?
Answer: DNA polymorphism refers to the variation in DNA arising through mutation at non-coding sequences. Since, polymorphism is the basis of genetic mapping of human genome ,therefore, it forms the basis of DNA fingerprinting too.
What is polymorphism in chemistry?
polymorphism, in crystallography, the condition in which a solid chemical compound exists in more than one crystalline form; the forms differ somewhat in physical and, sometimes, chemical properties, although their solutions and vapours are identical.
Why is polymorphism important biology?
How is the phenotype of an individual determined by polymorphism?
Three mechanisms may cause polymorphism: Genetic polymorphism – where the phenotype of each individual is genetically determined. A conditional development strategy, where the phenotype of each individual is set by environmental cues.
How is genetic polymorphism modified by natural selection?
Polymorphism (biology) It is heritable and is modified by natural selection. In polyphenism, an individual’s genetic makeup allows for different morphs, and the switch mechanism that determines which morph is shown is environmental. In genetic polymorphism, the genetic makeup determines the morph.
How is polymorphism different from monomorphism and dimorphism?
In biology, polymorphism has been given a specific meaning, being distinguishable from monomorphism (having only one form). A more specific term, when only two forms occur, is dimorphism. The term omits characters showing continuous variation (such as weight), though this has a heritable component.
Which is form of polymorphism omits continuous variation?
The term omits characteristics showing continuous variation (such as weight), though this has a heritable component. Polymorphism deals with forms in which the variation is discrete (discontinuous) or strongly bimodal or polymodal.
