Does mutation cause polymorphism?
Mutation is an alteration of the nucleotide sequence of a gene. If a mutation occurs in a population with a frequency of more than 1%, the mutation is called a polymorphism.
What is the difference between a mutation and a SNP or polymorphism )?
Polymorphism) is a type of mutation. Also, all mutations cannot be considered as SNP….Difference between SNP and Mutation.
SNP | Mutation |
---|---|
SNP is a change in the single-nucleotide of a genome. Also, it is a type of mutation. | Mutation is the variation in DNA base pairs caused due to insertion, deletion, duplication or substitution of base pairs. |
What is an example of polymorphism in humans?
All the types of blood groups are examples of genetic polymorphism, such as the ABO blood group system. We see this system having more than two morphs: A, B, AB, and O are the variants present in the entire human population, but these groups vary in proportion in different parts of the world.
What is DNA polymorphisms?
DNA polymorphisms are the different DNA sequences among individuals, groups, or populations. Polymorphism at the DNA level includes a wide range of variations from single base pair change, many base pairs, and repeated sequences.
What causes polymorphism?
polymorphism can be maintained by a balance between variation created by new mutations and natural selection (see mutational load). genetic variation may be caused by frequency-dependent selection. multiple niche polymorphism exists when different genotypes should have different fitnesses in different niches.
What is polymorphism and what are the causes of polymorphism?
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).
What is polymorphism in immunology?
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.
What is polymorphism disease?
Polymorphism–disease associations from different populations are extremely difficult to interpret. Different genetic variants contributing to the phenotype may be different in different populations.

What is Polymorphism?
What is a real life example of polymorphism?
Real life example of polymorphism: A person at the same time can have different characteristic. Like a man at the same time is a father, a husband, an employee. So the same person posses different behaviour in different situations.
What is the difference between a SNP and a mutation?
How is SNP different from mutation?
