What Is Polymorphic Gene?

A gene is said to be polymorphic if more than one allele occupies that gene's locus within a population. In addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic.

What is the meaning of genetic polymorphism?

Genetic polymorphisms are defined as the occurrence of multiple alleles at a locus, where at least two alleles occur with a frequency greater than 1%.

What is an example of genetic polymorphism?

Blood Groups. All the types of blood groups are the example 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.
