Question

10. Which of the following statements is

correct?
O Single nucleotide polymorphisms (SNPs) are not
found on the Y chromosome
50-100 SNPs need to be examined to achieve
the same discriminatory analysis as STR-based
profiling.
O Single nucleotide polymorphisms (SNPs) are
restricted to the autosomal chromosomes
O SNP analysis requires large amounts of sample
but it is useful where the DNA has become
degraded

Answer 1

The correct statement among the options provided is single nucleotide polymorphisms (SNPs) are not found on the Y chromosome. (Option A)

What is single nucleotide polymorphisms?

Single nucleotide polymorphisms (SNPs) are variations in a single nucleotide that occur at a specific position in the genome.

While they can be found on autosomal chromosomes, including the X chromosome, they are generally not found on the Y chromosome.

The Y chromosome typically contains regions with a lower mutation rate and a specific set of genes related to male sex determination and development.
