The pattern of DNA fragments generated by PCR amplification of “Short Tandem Repeats” (STRs), which are 4-40 bp regions of the genome known to vary in length between individuals in a population, is known as a DNA fingerprint. For which of the following real-world problems would the application of PCR-based DNA fingerprinting with STRs be most appropriate?
