NEET 2022, Biology Q26: Chromosomes and Genes

NEET2022Biology
Q.

DNA polymorphism forms the basis of :

  1. A

    Genetic mapping

  2. B

    DNA fingerprinting

  3. C

    Both genetic mapping and DNA finger-printing

  4. D

    Translation

Solution

DNA polymorphism refers to variations in DNA sequence among individuals of a population, typically arising from mutations or repetitive sequences (such as VNTRs and microsatellites).

These differences are exploited in two important applications: genetic mapping (locating genes by linkage to polymorphic markers) and DNA fingerprinting (identifying individuals from their unique pattern of repeats).

So DNA polymorphism is the basis of both.
