Which statement correctly describes single-nucleotide polymorphisms (SNPs)?
A) A SNP locus typically has more than two alleles.
B) SNPs are typically used as markers of a region of the genome.
C) The frequency of the rarer SNP allele must be less than 1%.
D) SNPs are the least common form of human genetic variation.
E) If only two alleles are associated with a SNP, both must have relatively the same frequency in the population.

Question

Quizplus · Accepted Answer

SNPs are commonly used as genetic markers in various studies, including genetic mapping, association studies, and identification of genomic regions linked to diseases or traits. They serve as points of reference that can help researchers track the inheritance of genes within families or populations. Unlike the other options, which contain inaccuracies regarding the nature and use of SNPs, the use of SNPs as markers is a well-established practice in genetics.
