Short tandem repeats (STRS) in DNA are often used in forensic analysis and for
determining paternity. What characteristic of STRS makes them useful for these
practices?
Every racial and ethnic group has inherited different short tandem repeats.
The sequence variation is acted upon differently by natural selection in different
environments.
The sequence of DNA that is repeated varies significantly from individual to
individual.
The number of repeats is highly variable from person to person or animal to
animal.
