In large scale, genome-wide association studies in humans, correlation is sought between
A) lengthy sequences that might be shared by most members of a population.
B) single nucleotide polymorphisms found only in persons with a particular disorder.
C) single nucleotide polymorphisms found in families with a particular introns sequence.
D) single nucleotide polymorphisms in two or more adjacent genes.
E) large inversions that displace the centromere.

Question

Quizplus · Accepted Answer

Genome-wide association studies in humans seek to identify single nucleotide polymorphisms (SNPs) that are more common in individuals with a particular disorder than in the general population. By examining a large number of SNPs across the genome, researchers can identify potential genetic factors that contribute to the development of diseases.

All of the other answer choices are either too broad (A, D, E) or too specific (C) to describe the types of genetic variations that are typically analyzed in genome-wide association studies.
