Q157 / 180 · NEET 2020 (Phase 2) · Zoology
Which is the basis of genetic mapping of human genome as well as fingerprinting?
- Correct answerAPolymorphism in sequence
- BSingle nucleotide polymorphism
- CPolymorphism in hnRNA sequence
- DPolymorphism in sequence
Solution
Allelic sequence variation is described as a polymorphism if more than one variant (allele) at a locus occurs in the human population with a frequency greater than . If an inheritable mutation is observed in a population at the high frequency it is referred to as polymorphism. Polymorphism in sequence is the basis of genetic mapping of human genome as well as of fingerprinting.
Hence, the correct answer is option: 'A'.
