Problem
ProblemThe goal of DNA fingerprinting is:
A
To collect DNA samples from random individuals in a population.
B
To diagnose diseases within closely related family members.
C
To determine whether DNA samples collected from two different locations are from the same person.
D
None of the above.

Problem
ProblemWhich of the following characteristics of short tandem repeats (STRs) makes it useful for DNA fingerprinting?
A
The number of repeats is highly variable from person to person or organism to organism.
B
The sequence of DNA that is repeated varies significantly from individual to individual.
C
The sequence variation is acted upon differently by natural selection in different environments.
D
Every racial and ethnic group has inherited a specific number of short tandem repeats.
