Which of the following characteristics of short tandem repeats (STRs) DNA makes it useful for DNA fingerprinting (genetic profiling) ?

A) The number of repeats at a particular STR is inherited following Mendelian genetic patterns.
B) The specific sequence of DNA that is repeated varies significantly from individual to individual.
