In DNA fingerprinting, which regions of DNA would provide the strongest evidence of a genetic relationship?
A)regions with noncoding and spacer DNA
B)regions that contain the genes for hemoglobin
C)regions that might contain genes related to personality disorders
D)regions that can be easily fragmented

Question

Quizplus · Accepted Answer

Regions with noncoding and spacer DNA, also known as variable number tandem repeats (VNTRs), provide the strongest evidence of a genetic relationship because they have high levels of variability and are unique to each individual, making them useful for identification purposes. Regions containing specific genes, such as those for hemoglobin, may be useful for diagnosing specific genetic diseases, but are not as effective for determining genetic relationships between individuals. Regions that might contain genes related to personality disorders are not relevant for DNA fingerprinting. The ease of fragmentation of DNA is not directly related to the strength of evidence for genetic relationships.
