What is meant by polymorphism in genetics?
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 genetics class 12?
Answer: DNA polymorphism refers to the variation in DNA arising through mutation at non-coding sequences. A special type of polymorphism, called VNTR (Variable Number of Tandem Repeats), is composed of repeated copies of a DNA sequence that lie adjacent to one another on the chromosome.
What does polymorphism mean example?
Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar’s skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed ‘polymorphism’.
What are different types of polymorphism in biology?
Polymorphism can be divided into two basic types: sexual dimorphism and allelic polymorphism. Sexual dimorphism occurs when there is physical, or phenotypic, variation between male and female members of the same species.
What are different types of polymorphism?
Types of Polymorphism
- Subtype polymorphism (Runtime) Subtype polymorphism is the most common kind of polymorphism.
- Parametric polymorphism (Overloading)
- Ad hoc polymorphism (Compile-time)
- Coercion polymorphism (Casting)
What are the properties of polymorph?
Polymorph is a thermoplastic material that can be shaped and reshaped any number of times. It is normally supplied as granules that look like small plastic beads. It can be heated in hot water and when it reaches 62 degrees centigrade the granules form a mass of ‘clear’ material.
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.
