Consider the following statements about Single Nucleotide Polymorphism (SNP):1. It is a type of DNA microarray which is used to detect polymorphisms within a population.2. SNP chips are DNA microarrays that test genetic variation at many hundreds of thousands of specific locations across the genome.Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C

Notes:

Single Nucleotide Polymorphism (SNP):

It is a type of DNA microarray which is used to detect polymorphisms within a population.
SNP chips are DNA microarrays that test genetic variation at many hundreds of thousands of specific locations across the genome.
SNP chips have proven to be excellent for studying common genetic variation, which can be used to assess ancestry as well as predisposition to many complex multi-factorial diseases.
