Final answer:

Tandem repeats (STRs) in DNA typing are highly polymorphic and unique to individuals, enabling precise identification in forensic science and paternity testing.


Explanation:

Tandem repeats, or repeating sections of DNA, are useful in DNA typing because they are highly polymorphic and unique to an individual. These repeats, known as short tandem repeats (STRs), are amplified in DNA analysis and used to differentiate individuals based on variations in the number of repeats at specific loci. This variability in repeat lengths allows for precise identification of individuals, making tandem repeats a valuable tool in forensic science and paternity testing.
