Question

How many of the given statements with respect to polymorphism are correct?
(a) Arise due to mutation
(b) Inheritable
(c) Helps in determining genetic and population diversity
(d) Basis of genetic mapping
(e) Helps in speciation and evolution

Choose the correct option

Answer 1

Polymorphism arises due to mutation and if it is in the non-coding part of the genome then it has very little immediate effect. They are inherited and accumulated through generations leading to speciation and evolution. Since polymorphism is very high in repetitive DNA, it varies from individual to individual in a population. Hence, it is used for genetic mapping and determining genetic and population diversity.
